Click ―Properties‖, It shows the set for actual printing ink out etc.( figure 7)
Figure 7
Print Mode: choose the printing configuration and precision according to the
actual print.
Dot Type: choose ―fixed dot‖ or ―variable dot‖.
Dot Size: When you choose ―variable dot‖, It will shows ―variable dot –dark‖,
―variable dot –standard‖ and ―variable dot –light‖, which shows the big dot,
middle dot and small dot mode for the ink dot.
White Enable: It is for choosing the white ink. When you choose this, The behind
option ―White Overlay‖ will brighten, ―White Overlay‖ means coat with white ink
first. It will print the white ink first for coating before printing the pictures. If you
don‘t choose ―White Overlay‖, It means to print the other colors ink except white
first for the picture, and print the white ink later. It mainly used for printing glass and
other transparent materials.
Varnish Enable: It used for the material which need to print varnish. It has 2
models,too.but rarely used
4. Physical Connection Interface
12

Choose the Physical Connection interface to connect your printer in

Connection interface‖ and add physical connection interface.
5. Screen Setting
After setting ―Printer model‖ and ―Imaging Configuration‖, please choose Physical
Connection interface which connect with your printer in Wasatch SoftRIP. The
following details for the remaining settings
Paper Margin: Normally it means the max printing width of the printer, But you can
manually enter a smaller value for smaller media It‘s particularly important to
specify the correct media width if use SoftRIP to edit and tile
13

Paper width: It usually stands for the Max printing width assigned by the printer.If it
is a narrow printing media,you can input a small width. If you use the layout and
jigsaw function about SoftRIP,It is very important to set a exact media width.
Scale Adjustment:It is use to associate with a small scale percent for the given
printing unit.This Scale percent is to compensate the deformation during the
special printing procedure.
Crop Marks:It will place on all the printing media with corner marks to help the
adjustment.If choose ―Full Length‖,It will make the crop marks like a line extend to
the whole picture makeit easy to cut.For tile job,This marks will indicate the gap
and secant for overlapping.Reclaiming line will be printed as a liny solidline.But the
overlap gap will show as a dashed line.
Register Marks:It will create angular register marks on all the printing media.It is
very useful when you use Wasatch SoftRIP to make the color separation.
Annotate prints:It will print the extra information for the job in the bottom.If choose
―Annotate prints‖, It will active ―Annotation details‖ as figure 8.
For most of the high resolution inkjet printers,It will generate the clear words if one
inch print 8 lines,and save the paper at the same time.For the low resolution
printing mode,the printing result will be better if one inch print few lines by using
bigger typeface.the most is to print 6 lines.
Input the notes which need to be added to the annotation in the ―Unit Note‖
window,this words will be printed on the job.If you want to input the words which
14

print on the special job,Please input a ―Job Note‖ word on ―queues‖ edited
window.If you input 2 notes,it will print the 2 kinds of word at the same time.
CMYK Vector Test Pattern: It will add the predefined test pattern into printing
annotated information.The test pattern will print with the same CMYK Vector color
management for main picture. It is very important to make sure the quality for
color‘s workflow(include mimic coloration)
Cutting Option: It controls the cutting function in SoftRIP‘s selectable outline
cutting function. Before choose selectable ―outline cutting‖ module, all of the
setting will show in gray. For details, Please view the online help.
6.Unit Options:(figure 9)
Some key print unit setting is in ―Unit Options‖. You can visit this setting
conveniently.The setting is specially designated to the print unit. You can change
the unit throught the setting.
Immediate Print:
figure 9 :Printing method
After RIP and generate pictures,It will print immediately.If you cancel to choose
the frame,then it will print after RIP the whole picture.When you choose
―Immediate Print‖,as the machine will wait for the RIP date,so maybe the printer
15

will pause when printing.For some printer,It will affect the printing quality.So don‘t
use immediate print when printing the page.
Hold for layout:
If you choose ―Hold for layout‖,the job will start to print through the queues after as
part of the layout is put into print. Then can choose to send part and click ―queue
nesting jobs‖ on the ―print queue‖ to send all the jobs to the ―layout‖ screen.
Notice ,this selection will only stop individual task not printing pages.
Single Row Nesting:
This auto- Row Nesting function don‘t need connect to printing procedure, so it is
good for saving media. The system will save the printing job till it has enough
picture to satisfy media width in the queues. The setting date in the ―Gap‖ window
will decide the distance between tiled pictures. If you want to print the tiled job
before filling the media width, please click ―Force Nested Output‖ bottom.
7.RIP the workflow job and print:
If you want to create a printing, SoftRIP will RIP the picture first,and transmit it to the
printer.You just need to click the printer bottom on the ―Tools‖.When doing RIP,it
will start ―PostScript‖ interpreter in the taskbar, and send the date of ―Fake offline
printing manager‖ to the printer. Click the ―PostScript‖ or ―Fake offline printing
manager‖ will open the window show progress of the operation.
Important contents!
Please make sure to choose ―Queue Processing Active‖ at the top of the
screen. When you cancel it,the system will fulfill the processing job,but won‘t
start dealing new job.When you need to stop the job urgently, this safe set
is useful.But if you forget to choose it,it will generate some problems. If cancel
it,it will show red light and show ―Queue Processing Not Active‖. The job can’t
be Ripped and printed if you cancel “Queue Processing Active”.
Add to RIP queues but don’t RIP:
If you want to add a job to RIP queues for dealing in the future,please choose
―Add to RIP queues‖ in ―Print‖ menu. Then the job will be added to Rip queues, but
won‘t be Ripped.

start Postscript interpreter. After fulfilling. The job will be in a separate line in ―print
queues‖, and its quantity is 0.
RIP and Print:
When you choose ―RIP‖ from the ―print‖ menu or click the ―print‖ button at the
toolbar, SoftRIP will fulfill job according to the above way.The only different is the
job will show in ―print queues‖ and its quantity is ―1‖.If you don‘t choose any
special unit options to delay printing. Your job will print start sending to the output
equipment immediately after the last job is done.
8.Adoption of typesetting workflow RIP and printing
After layout has been sent to RIP, Wasatch will RIP every image separately .Then
an entry that represent the whole layout will appear in the printing list, at the same
time, the entry of images that have not experienced RIP will also appear in list.
Before all the pictures are Ripped it is not be able to check or print the items in the
―print queue‖.
After ―RIP and print‖ has been chosen from the main menu, the items representing
layout in the ―print queue‖ would show the number 1. All layouts would be sent to
printer directly after having experienced RIP .The button ―wait for completion of
typesetting‘ in ―Unit Options‖ will not stop the whole process of printing.
If the layout includes the tasks has been Ripped, those tasks will not be Ripped
again, sometimes, there is many copies of images that have not experienced RIP
and those copies are different, perhaps one of copies is rotated and resized.
System will generate new entry list for every unique image.
If any component file in the list has been deleted, the layout will not be valid.
When you try to cancel file in print list,, system will warn you that it is one part of
layout printing, the layout will not be valid anymore after it has been canceled.
If you click ―yes‖ at this time, you can‘t access layout that is not valid anymore.
9. Basic information of main list manager
17

The main list manager can help you control the situation of every task in the
process of printing. Click ―print unit‘ frame on the top of option card, you can
choose to view the list you want to check. Clicking ―tool‖ button on some RIP print
list will start setting screen for this print list. To view more than one unit, horizontal
direction is more convenient, to view print list of one printer, use vertical direction
will be more convenient.
Operation of dragging main list
If it is not necessary to prepare any files for image, you can drag it straightly from
‗document scanner‘ to RIP list. The system will ask you whether to generate the
preview. If choose no, it will show ―no preview‘ after image is added into layout.
To speed up the process, you can drag and drop file between lists. Whenever you
drag an entry into print unit that have different settings, the system will notify you
that you must use setting plan of target unit to RIP this file. When drag it to print
list ,it will be sent to RIP list and the ―Edit" window of RIP list will start automatically.
Click" to print whenever there is chance ―and choose the number of copies you
want to print so that it can start printing task and send it to print list.
10. Deal with RIP list
When task is in the situation of waiting for processing, it will display "R" in RIP list. If it
is sent to RIP and ready to print, it will show the number of printing in "Number list ".
If it shows 0 in both of the two lists, it means it has not been sent to RIP yet or it has
already experienced RIP. Please be noted that the entry in the list includes
information of source file location and revised information of image in SoftRIP.
18

Suppose the source file has been moved or canceled before RIP course, the
image would not be processed.
When choosing a certain task in RIP list,it will activate other buttons that are
specific to this list in tool bar. To change the settings, you can change it through

1. The carriage back to the origin:
Chapter 3 Solution for offline
Carriage moves slowly to the right →original blank insert into the origin sensor→
carriage moves to the left → move a short distance to the left after the carriage
stops.
After turned the printer on, the carriage will come back to the origin and then
moving slowly to the right. It will continue move until the origin sensor senses the
carriage blank. But the fact is that the carriage will move left further distance for
origin parameters we have settled in software. The machine online after the
carriage finished this distance
2.Settlement of offline situation
(1)Check whether using the wrong software or not. A typical features of using
wrong software was the machine power with online, but it will display "OFFLINE"
once pressing the arrow keys. Beside the left side of damper ,there is a white ink
stack, these models which board A, B are the upper and lower plug are named
" "driver. While there is a Square motor control
blake alone beside the left side of damper, these models which board A, B are
the left and right plug are named" "driver.
(2)Second,shutdown → restart software → Power on
(3)Check whether Epower USB driver is being properly identified or not
(4)Reinstall the printing driver
23

(5)Put the carriage onto the middle of the printing panel: ① If the carriage does
not move but it can work by blocking the origin sensor with a card. In this case,
maybe it is about motor, motor drive board problem. ② If the carriage move to
the left, maybe something wrong with the origin sensor or the cable is not
well-connected. ③ If the carriage keep moving to the right until it hit the right
bezel, you need to check whether the the blank position of the carriage can
inserted into origin sensor or broken origin sensor.
(6)Change a computer
(7)Main board issues
Chapter 4 Software
1. Original set,print original location set, flash jet location set method:
Entre engineer mode(code:XENONS)first,and then entre the setting of
calibration parameters。You can set length,original point,print original location
and flash jet location。But in this mode the unit is point,1mm equal about 7 dots。
2. Horizontal gear ratio setting:
First use WordPad to open config file in the software,and then find step_to_mulse
in the config parameters ,is 49518

First use WordPad to open config file in the software, and then find Vert Motor One
Step Length in the config parameters, is 354609
4.Horizontal motor speed parameters setting:
First use WordPad to open config file in the software,and then find:
5. Vertical motor speed parameters setting:
Adjust these three numbers to
the same, normally suggest
28,max 33.the larger of the
value, the faster the carriage's
speed will be.
Please open config in the software by using tablet.Then you can find below
The faster the carriage’s speed
specifications:
Adjust will these be. three number to
24
the same Normally suggest
26,max 50.the larger of the
number the faster the paper
will be.

Notice:when any of the setting is changed must restart the software, or the setting
will not be valid
Chapter 5: Adjustment for XENONS 4740/8740 Service Station
Adjust Service station : adjust service station to the best condition according to
front- back ,left–right, up and down positioning .
1.Adjust the height of service station :
First lower the carriage to 1mm between the print head and cap.
25

the two legs
and printhead
should be
much closer ,
2. Adjust front and back of service station:
When carriage is pushed in , the two legs and printhead should be much closer ,
but do not touch print head , you need to loose the screw which fasten the
service station , and move service station back and forward .
3.Adjust left and right of the service station :
You need to adjust origin position good , through adjust the catch of origin
position to realize physical adjustment ,when the carriage stop at origin
position ,the distance between service station round horn and slideway corner is
about 3mm .

Adjust front and back of service station : when carriage is pushed in , the two legs
and printhead should be much closer , but do not touch print head , it needs
loose the screw which fasten the service station , and move service station back
and forward .
37
You have to lose these screws
before para-position
But the two
angles
should not
scrape print
head

The adjustment of service station cap: You need firstly loosen the screw of fixing
service station cap,put the cap in the middle of print head and then fix it. Adjust
the origin baffle to make the distance between round angle of service station and
corner of slide slope is about 3mm.
It is ready to print image after this series of adjustment.

3.When fill the ink,the ink should not be over the damper filter,please use injector
to control the ink level to reach about 2/3 position of the damper。When pump
ink , insert damper in print head firstly and then pull out one damper and use the
injector to pump it。Then insert it to print head again. when pump ink, the ink
nozzle that is inserted in the print head should be upward,and then use the
injector to pump ink。

1.When plug the printhead data cable, it must be in the right order。The front part
of the cable should not be winkled。When use injector to pump the ink , the ink
should not drop on the data cable at the front part of the printhead,to avoid the
ink getting into printhead and burn the head when power on。
2. Air leak is not allowed at where connect with damper.
3. When use the injector to suck ink, air bubble should not be existed in the
bending groove of damper。
4. When install the damper plate, the damper plate should be compressed hard.

○3 . Attention:
1. V1.0 boards are green, V2.0 boards are blue.
2. Main board A is green and can be used on 4740 and 8740. The color of the
main board B should be matched with printhead board's:
A. if the main board is blue, the printhead should be the same color.
B. if the main board use V2.0, the printhead should use V2.0 too.
3. If you mixed the green one and blue one up, it will cause board burning or
other serious bad consequences
4. The different between 4740 main board B and 8740 main board B
The mian board B v1.0 of (green) of 4740 and 8740 could be use in common, but
the mian board B v2.0 of (blue)4740 and 8740 could not.
Their major difference is the jumper.4740 motherboard B jumper lie in B2 foot, while
8740 mother board B lie in 0 feet.4740 motherboard B have (DX5 non-R)labels on it
and 8740 motherboard B have (840 / 841) labels on it.
4. The difference between model 8740ASW/ADW and model 8741ASE/ADE
A. Different in printhead:8740ASW/ADW are 7840 heads and they have an
oil-based labels of 7840.
8740ASE/ADE are 7841 heads and they have red labels on them.
7840 and 7841 heads can not be mixed, otherwise it will cause board burning and
head burning or other serious bad consequences
B. different in printhead board:8740ASW/ADW use 4740D-B heads.
8740ASE/ADE use 4740D-C heads.
4740D-B and 4740D-C board can not be mixed, otherwise it will cause board
burning or other serious consequences
54

5. All printheads of 4740ASW 4740ADW 4740ASE 4740ADE use 4740D-A, as
mentioned, the color of the main borad B should be matched with printhead
board's color, never mix up.
Chapter 12 The method of solving the deviation in
media feeding processing
The deviation problem of feeding shortage and over feed mostly happened on
the outdoor machines, cause the material used on the outdoor machines is very
heavy and would bring about the situation of feeding shortage. After our testing,
now supply you the way how to solve this problem:
Method 1: decrease the stepping motor speed, the modification as following:
Open the software folder, find , then open it by tablet, then to
search for
the default speed is the highest speed 50,you should change to26,after
changing
(avoid by all means: must save after changed, and restart the software, then it
could be efficient)
Method 2: Reduce the resistance of the media feeding system,to feed the media
more smoothly and uniform the resistance. That is: Remove the resistance
55
,
。

device of the heavy media feeding system, add Grease on the central rolling
parts of the media frame, method as follow:
First open the outer covering of the media frame, then remove the white
gearwheel.
Remove the three
related screws
here.
2,Add Grease on the central rolling parts of the media frame of both sides.
Add grease
around this
white parts.
Method 3: Step adjust according to the media which the machine is printing,
method is as follow:
1,First contact the machine with computer,right click this button ,
entre the “print engineer mode”,entre the password “XENONS”,right click
this button again ,entre“adjusting parameter setting”.shows the
window as follow:
Click vertical adjust,shows the window as follow:

contact point.
Click vertical adjust
纵向校准

Mark here with
“√”,“200”will
automatically light
up,change it
to2000,click
“save”,and click
“yes”。
2,load the media,find a certain place as a reference,and mark this place,then
press the“down key”on the key board and hold,till the machine stop
automatically,use the ruler to measure the length of the media running. use
―mm‖ as measure unit.
3,use 2000 divided by this length that the media runs,then multiplied by 354609,
fill the results to (Excluding the value after the decimal point) ―Vert Motor One
Step Length =‖ find in .save after change,and restart the
software.\
According to different situation,you can choose one of the above method or use
all。Notice:the maintop that now used have a automatically blank jump
function,that means software will jump the blank area,this cause the print
media turns short. Customers can stroke the blank area and also can change
the ICC of maintop to non- blank jump function version. We have already
adjusted the ICC of this version, please contact the factory if you the customer
need it.

Chapter 13 Same Color and Different Colors Adjustment
In order to make the head position of double heads printer more accurately, and
improve print quality, we need use "same color adjustment" instead of "different
colors adjustment" in ―Head1—Head2‖of the key board ―(MENU)‖.The ways of
Same color and different colors adjustment are as follows:
○1 .same color adjustment
After the computer is connected, please right-click the xenons driver software
icon on the bottom right corner of the computer, select the print engineer
mode, and then there will come out a dialog box (Figure 1.1), enter the
password XENONS, click OK to enter the print engineer mode.
Figure 1.1
After starting print engineer mode,click the same color adjustment (Figure 1.2)
58
Enter password
“XENONS”
Click here for the same color
adjustment

(Figure 1.2)
Then the printer will show this adjust picture on the paper(Figure 1.3)
(Figure 1.3)
Take the cyan for example, the figure 0 is not aligned, -1 alignment.In this case,we
need choose the same color calibration in calibration parameters (Figure
1.4),and then choose to modify parameters in the C Division (like Figure 1.3,the
figure should be reduced 1 on the basis of the original parameters), the
selected color and direction should keep correspondence (L-R corresponding
to "→", RL corresponds to the "←" ), and only modify the parameters of 2-3.C
Division 2-3 parameters should be changed from 739 to 738. Other colors
calibration just the same with cyan.
59

After modified all
the parameters,
please save.
(Figure 1.4)
After modified all the parameters, and then repeat the operation in Figure 1.2 until
all the color adjustment date 0 ( Figure 1.5)
(Figure 1.5)
○2 .different colors adjustment
After starting print engineer mode,clicking on different colors adjustment, and
then it print different colors graph (Figure 1.6). Each color take the black as the

ase, increasing or reducing the points to keep other colors alignment with
black 0.
(Figure 1.6)
We need modify colored calibration parameters according to the calibration
graph.Enter into calibration parameter selection to chose different colors
adjustment (Figure 1.7).Please note √ at the benchmark parameters dialog
box ,and it will display
like Figure 1.8.And then according to the position with the black to do addition or
subtraction process, until all the color adjustment date balck 0. (Please pay
attention to the direction: L-R corresponding to "→", RL corresponds to the "←" )

Chapter 14 Routine Maintenance of Printhead
○1 Routine maintenance of water based machine:
1. Firstly keep the machine cleaning, when the machine not in use, should push
the carriage to the original place, let the printhead and service station cap
cling closely, keep the printhead enclosed in the service station cap.
2. When off-duty each day, push the carriage to the original place, keep the
printhead enclosed in the service station cap. The next day clear up the printer,
you could start to print after wipe the dust from the printer,
3. When the machine not work over four days (include four days), before resting
machine, you should pour a few suitable cleaning liquid into the service station
(drip little cleaning liquid, which should be suitable that just fully humidity the
service station cap sponge, but never filling up), then push the carriage to the
62

original place, must keep the surface of printhead and the service station cap
cling closely.
○2 Routine maintenance of eco-solvent machine
1. The same as water based machine, keep the machine clean, when the
machine not in use, should push the carriage to the original place, let the
printhead and service station cap cling closely, keep the printhead enclosed in
the service station cap.
2. When off-duty each day, push the carriage to the original place, keep the
printhead enclosed in the service station cap. The next day clear up the printer,
you could start to print after wipe the dust from the printer,
3. When the machine not working over there days, should clean up the peristaltic
pump and the service station use of the eco-solvent cleaning liquid, thus the ink
pipe in the peristaltic pump could not coagulate, then pour a few suitable
cleaning liquid into the service station (drip little cleaning liquid, which should be
suitable that just fully humidity the service station cap sponge, but never filling
up), push the carriage to the original place finally.
4. When the eco-solvent machine not work for long time, you'd better unload the
printhead. Before unloading, clean up the printhead use of the eco-solvent
cleaning liquid, wrap the printhead with non-woven fabrics, dip the fabric in
cleaning liquid, wound tightly with preservative film outside. As the same must
clean the service station cap and the peristaltic pump.
5. When the printhead dogged or blocked cause of not working for long time, try
to soak the surface of printhead in the eco-solvent cleaning liquid for a while.
63

Attn: it is better for the eco-solvent machine to print more than 20 minutes every
day.
Chapter 15 Daily Maintenance and Notice of Printer
64
If the machine not work
for long time, when
keep the printhead
humidity, should drip
little cleaning liquid,
which should be
suitable that just fully
humidity the service
station cap sponge, but
never filling up

To keep normal working situation of printer and make sure its constant and
high-quality output, daily maintenance is a necessary step,The right maintenance
steps are as the follows:
1. The printer and the surrounding working environment must accord with the
requirement for equipment.(Temperature:20-30℃,Humidity:40-60%),and the
surroundings should not have the equipments which have strong magnetic field
and may cause a lot of dust.
2. Keep printer clean,operator should do normal cleaning work.( blade and purge
pad need to be cleaned frequently)
3. In process of using,You have to keep platform clean without foreign matter to
avoid scratching the surface of print head.
4. After long time working, the around of print head should be cleaned. To keep
the around of print head clean without condensed ink.
5. On the rail guide,The foreign matter is not allowed to exist, otherwise, it would
damage rail guide and slider,even broke the print head. Usually, it's not necessary
to add oil to rail guide, if it need adding oil, please use oil of sewing machine and
not too much to avoid flowing to printing materials.
6. Ink cartridges should be well covered after adding ink ,to prevent dust or other
foreign matter fall into it and cause ink blocking.(when add ink,ink cartridge
should not be taken out ,to prevent parts inside broken because of frequent
plugging and taking out ,and cause unnecessary loss )
7. Eco-solvent ink can't be mixed with water. Otherwise,it will cause chemical
reaction and generate sediment ,which can block the print head. Blade needs to
be replaced to a new one when it is dirty.
8. Install print head baffle plate firstly when removing the printer.
9. Operate printer strictly according to our operation instruction, otherwise, it may
cause unnecessary loss.

3.The output voltage from power board to motherboard is(42V、24V、5V),The
output voltage from Power board to motor board is (42V、5V),The voltage for fan
is(24V).
4.The order of ink color in cartridge for Dx5 printer is(K、C、M、Y)(stand at the
back of the printer,from right to left).The order of ink color in damper is(K、K、C、
C、Y、Y、M、M)(stand at the back of the printer, from right to left).
5.The color for back paper detector‘s line is green,grey and black, if need to short
connect,which 2 color lines should choose?(grey black)
6.When change parameter in config, the speed of carriage should change to
(Motor_Speed 100,250,330),The speed for entering media should change to
(Vert_motor_speed 1,2,3).
7,For carriage‘s transmission belt,we have two colors: white and black, Gear Ratio
for white is (50408),for black is(49518);if customer‘s printer has black belt,but set
white Gear Ratio,which situation will appear:
(1,when printing the first pass, the carriage will stop when reached the left side
and slow down and move a little distance.)
(2,it will appear 0.5cm dislocation when pause and print again)
(3,when to clean after pause, the cleaning result will be very bad)
8,If the wiring is correct, the carriage will move slowly to left and stop and then
move, the most possible problem is (the grating decoder haven‘t read the raster)
66

9,When it hasn‘t ink in the ink pipe,if one of the ink sac leak air, can it fill the
ink?(cann‘t fill ink)
10.What are the conventional media printing width for indoor printer?
(1520mm,1370mm、1270mm、 914mm.)
11,when the USB cable is not connected, the carriage cann‘t be locked by itself
after open the machine ,the most possible problem is (motor)board.
12.We always say printer‘ 7 dots is 1mm, how do it come?
(each dot is 0.141mm, 1 divide 0.141 is about 7.09)
13.What is dpi?
Dpi means how many dots in each inch
14.In maintop software, the pictures save as (TPF)format after mading,It is (pm)
format after RIP.
15.For our printers,74 inch machine has the max width for media (1.88m),the max
printing width is (1.8m);50 inch machine has the max width for media(1.27m),the
max printing width is(1.27m).
16.When install the eco-solvent machine in factory,We should use(pure water)to
clean the ink system.
17.During printing,the carriage will stop longer time when it moves to the left and
right side,especially when RIP and print is in the same time,what‘s the reason?
Because(the computer‘s RAM is not enough)
18.When the 4740-A machine is printing,It will appear the lines which has the same
width with printhead in picture occasionally.It still exist after changing the driver for
motherboard.How to solve this?
(to tie all of the long flat cable together,to avoid them move in the towline)
19.During printing,It will appear the carriage stop in any positions,we push the
carriage in this situation.
If the carriage can be pushed to move,Then how to analyse it?
67

(It is the problem for power board.Because the carriage can be pushed to
move,It means it hasn‘t relation to computer and USB cable.And it is normal when
restart the machine again. It hasn‘t relation to motherboard ,motor board and
motor)
If the carriage can not be pushed to move, how to analyse it?
(It is the problem for computer,USB cable and software.The machine can
connect and print normal after restarting every time .This means the control
system is ok,The carriage can lock by itself when printing stop.This means it is not
the problem for motor loading.Expect these factors, it may be the following
problems: the computer RAM is not enough,the USB cable isn‘t connected
well,software dead and so on.)
20.When connecting the printhead date cable of DX5 inkjet printer,If insert upside
down,Then (the motherboard and print head will be burn at the same time.)
21.For Dx5 machine, if it often appears break lines during printing,how to analyse
and solve it ?
①The machine offen appears off-ink .
Check if there is air which haven‘t left out at the location for inserting ink needle in
ink cartridge.
Check if the ―O‖ type circle in the copper bush is neglected or broken.
Check if the printing material can cause large static electricity.which will make
the ink adsorbed in the surface of printhead.Then it will appear ink break.And it will
appear some times after cleaning.And it can exist any strong magnetic
equipment or dust-attracted equipment.
②When the off-ink happens,the machine can not be cleaned well.
Check if the ink needle is blocked.Check if the connections between the ink pipe
and the interfaces are not good or broken. especially the hard pipes. Check if the
ink sac is damaged or leak air. Check if it is the problem for the service station
itself.
To check if the ink system goes smooth, If there is some scratch or block for the
surface of printheads.you can try to soak the printhead into the ink.
68

③Check whether there are air bubbles in the ink supply system or not.It can result
off-ink if leak air.
④The pad of flash and the pad to press paper is too high,Which may hit the
surface of printhead to cause off-ink during the carriasge moving.
⑤The blade hasn‘t install,or install upside down,or broken.
⑥Temperature will also affect the off-ink ,you must keep the machine and its
surrounding environment match with the requirements of the device
(temperature :20-32 ℃, humidity :40-60%).
22.When received the call from customer‘s engineer,he tells you that the VH light
on printhead board is off, how would you guide the customer‘s engineer to solve
the problem?
Answer:
Power off the machine and try to learn the detail about the machine. Does the
machine suddenly have the problems in the normal situation or have the
problems after do some adjustment and deal.If it has the problem suddenly in the
normal situation,Then Please follow the below testing procedures to check. If the
second situation,You sould analyse it depending on different situation.
The reasons to cause this problem:
1. Power board broke,which causes that power board hasn‘t 42V voltage output
to motherboard.
2. Motherboard broke, which causes that power board has 42V voltage output
to motherboard.But the motherboard hasn‘t 42V voltage output.
3. Long Flat cable has problem,which results the 42V voltage hasn‘t transmit to
printhead board,but the mother board is OK.
4. Printhead broke.
5. Printhead is short, which results the mainboard burned out. It maybe the
boards is short inside the printhead at this situation, or maybe the printhead
connector has has put the ink in.
The checking methods for customer’s engineer:
Unplug the USB cable.
69

1. Unplug the power cord of power board from the motherboard .To check if the
voltage for 42V, 24V, 5V is normal.
2. To check if there are some metal like screws,water and other conductive
materials on the board.
3. Check if the long flat cable has split, insert wrong place and damage.Check if
the other cables plug wrong pace or connect bad in the boards.
4. Check if the printhead connector has put ink in,which cause the short.It needs
to put off the printhead and check.If all of them is good,you can change a
motherboard.But before charging,Please unplug the printhead data cable
from printhead board. Check if the VH light on printhead board is on after
open the machine.It it is on,then you can check the movement and check if it
is normal.Turn off the machine after testing,and connect the printhead date
cable. And test if 3.3V, 5V, 42V in printhead board is short with ground.if it is
short ,This proves the printhead is shor.Then you can not turn on the machine
before changing a print head.If not,Then you can connect the cable and
open the machine.
23. During the printing process, if one side is jamp space and another side
overlape,and it change periodically, how to analyze and handle it?
Answer:
Analysis:If one side is jamp space and another side overlape.It is because the
different in entering paper on left and right side.And this phenomenon is often
changed periodically.When the left side enter more paper than the right side,the
left side will occur jamp space while the right side will occur overlap; But when the
situation reaches a certain degree,the more paper entering side will be pulled
tightly to the paper tube sections, the less paper entering side will become loose.
And then further, the tight side go less because the resistance, on the contrary, it
will go further on the loose side.This cycle continues to form one side jamp space
and the other side overlap. and the jamp space side will overlap while the
overlap side will have jamp space.And they change periodically.
Solution:
1. Check whether the material is well-installed or not,and check whether the
frame is installed at the same left-right level.
