2 Chapter 1 – Introduction<br />
<strong>Lotem</strong> <strong>400</strong> Overview<br />
The <strong>Lotem</strong> <strong>400</strong> platesetter is a Creo thermal imaging platesetter. It<br />
represents state-of-the-art technology within all operational systems, and<br />
features a technological breakthrough in the form of a multi-beam,<br />
variable resolution thermal imaging head. Within the footprint of a typical<br />
4-page imagesetter, the <strong>Lotem</strong> <strong>400</strong> platesetter with optional multi cassette<br />
unit (MCU) provides full automation including slip sheet removal,<br />
customized plate punching, and plate loading/unloading. It has a fast<br />
rotating external drum and a thermal imaging head.<br />
The thermal imaging head inside the <strong>Lotem</strong> <strong>400</strong> platesetter is comprised of<br />
a 24 laser beam array operating at a wavelength of 830 nanometers.<br />
Individual beams are precisely positioned using a self calibrating<br />
alignment configuration, and this allows for continuously variable<br />
imaging resolutions.<br />
A significant and unique feature of the <strong>Lotem</strong> <strong>400</strong> platesetter is dynamic<br />
drum balancing which guarantees rotational stability of the external drum.<br />
The supported plate size range, around the drum x along the drum, is from<br />
minimum 311 x 228 mm (12.25 x 9 inch) up to maximum 622 x 750 mm<br />
(24.5 x 29.5 inch).<br />
To allow for variable resolution imaging, drum rotation speed is<br />
programmed to vary proportionally with the output resolution. This<br />
particular feature is unique to <strong>Lotem</strong> <strong>400</strong> platesetter, and ensures<br />
optimized imaging speeds based on output parameters.<br />
The <strong>Lotem</strong> <strong>400</strong> platesetter front end is the Brisque or Prinergy. In addition<br />
to standard Brisque Impose features, special features for CTP users, such as<br />
fast plate remake and back/front preview were added. The <strong>Lotem</strong> <strong>400</strong><br />
platesetter system can accept data from any standardized digital file format<br />
including PostScript, EPSF, PDF, TIFF-IT, and CT/LW files.

The platesetter room may include:<br />
• <strong>Lotem</strong> <strong>400</strong> platesetter<br />
• PC Controller monitor; the user interface of the PC Controller that<br />
controls the platesetter operation.<br />
• Workflow workstation; jobs for the <strong>Lotem</strong> <strong>400</strong> platesetter are processed<br />
by the workstation.<br />
• Conveyor; moves the unloaded plates to the Processor.<br />
• Processor; option not supplied by Creo and intended for plates that<br />
need processing after expose.<br />
Note: The Plate stacker (for collecting unloaded plates) and Pre-heat oven (for<br />
plates that require heating), not supplied by Creo, are not shown in the figure.

Turning the Platesetter On and Off<br />
To turn on the <strong>Lotem</strong> <strong>400</strong> platesetter:<br />
Important: When power is interrupted, the platesetter shuts down. To<br />
continue working when normal power returns, you must press either of<br />
the two yellow on/off pushbuttons twice (once to “turn off” the<br />
platesetter and once to turn it back on) as shown in Figure 2 on page 4.<br />
The pushbutton lights up and the platesetter restarts.<br />
Note: Turn on the platesetter before turning on the workflow workstation.<br />
1. Check the air pressure gauge (see figure below) in the air pressure unit.<br />
Make sure the air pressure is 6 ATM (88 psi).<br />

Overview<br />
The PC Controller monitor is your interface with the <strong>Lotem</strong> <strong>400</strong><br />
platesetter; it monitors the platesetter operation, is constantly updated<br />
with the machine status and provides machine information. The<br />
platesetter is controlled by the PC Controller located inside the platesetter;<br />
the monitor resides on a nearby table, as shown in Figure 3 on page 5. The<br />
job data is sent from the workstation, that is connected to the PC<br />
Controller (see Figure 4 on page 7).<br />
Figure 6: PC Controller monitor
User Interface 13<br />
User Interface<br />
The PC Controller monitor is your basic working area, where the<br />
application indicators, buttons, popup menus and windows appear.<br />
The workflow-oriented platesetter user interface is intuitively designed,<br />
and minimal computer knowledge is required. The following features<br />
support this design:<br />
• Color-coded Status indicator indicates the machine status. For<br />
example, if a problem occurs while you are away from the monitor<br />
checking exposed plates, the problem indications on the screen are<br />
visible from a distance.<br />

Loading Plates<br />
Loading Plates via the Workstation<br />
The <strong>Lotem</strong> <strong>400</strong> platesetter has a semiautomatic plate loading process.<br />
When an expose job is initiated by the workstation the requested plate is<br />
placed at the center of the loading tray, emulsion side down. When the<br />
Loading plate pushbutton is pressed and the machine is ready to expose,<br />
the plate is automatically loaded into the platesetter.<br />
1. Define an Expose job on the workstation (see Brisque to <strong>Lotem</strong> <strong>Family</strong><br />
Connectivity User Guide, 399Z3R084A).<br />
2. A message is sent from the workstation to the PC Controller<br />
requesting that an appropriate plate be loaded in the platesetter. The<br />
message on the application Main window specifies the plate thickness<br />
and size.<br />
Figure 10: Message on PC Controller sent from workstation<br />
3. Get the requested plate.<br />
4. Place the plate on the loading tray (emulsion side down). Note the<br />
printed vertical scale on the tray; its numbers are plate width sizes.<br />
Make sure to align both sides of plate with the scale markers that<br />
correspond to plate width.

Plate Geometry<br />
This section describes aspects of the plate geometry and image area. These<br />
aspects will help you plan for the plate exposure process and define correct<br />
settings for your press and plate, and your image offset.<br />

Figure 15: Negative working plate – various plate dimensions<br />
Head margin – defined on the workstation, as one of the press format<br />
parameters. It defines the distance from the plate edge until the beginning<br />
of the layout or the exposed image. This parameter is also known as leading<br />
edge to print.<br />
Tail margin – defined on the workstation as one of the press format<br />
parameters. It defines the distance from the back edge of the plate to the<br />
edge of the file or layout.<br />
H (height) – plate height (around the drum).<br />
W (width) – plate width (along the drum width).
Plate Geometry 31<br />
In a negative exposure of a positive working plate, there is always an<br />
emulsion area on the plate that is not exposed, therefore emulsion areas<br />
remain. The size of these areas is determined as follows:<br />
• At the head, the area is equal to the width of the plate and at a height of<br />
up to 10 mm.<br />
• At the tail, the area is equal to the width of the plate and at a height of<br />
up to 6 mm.<br />
The image alignment is determined by the Alignment, as defined in the<br />
Plate Expose window on the workstation. For details, see the Brisque to<br />
<strong>Lotem</strong> <strong>Family</strong> Connectivity User Guide, 399Z3R084.

• What was done since then? For example:<br />
<br />
<br />
<br />
Was the machine moved?<br />
Was the machine cleaned?<br />
Was a new batch or type of plates used?<br />
• Was an error message displayed on screen? If yes, what did it say<br />
(include numbers, if any).<br />
• What is the software version?<br />
• Does the problem happen all the time (with all plates), or just some of<br />
the time? For example:<br />
<br />
<br />
With a particular plate brand, type and/or size?<br />
Only when a few plates are left in the cassette?<br />
• Does the problem seem to be a random occurrence?<br />
• What are the temperature and humidity levels in the plate storage<br />
room? For example:<br />
Do they adhere to the plate manufacture’s guidelines? If not:<br />
• In what ways?<br />
• Does the temperature fluctuate radically?

Plate Loading Failure 37<br />
Plate Loading Failure<br />
Releasing Stuck Plates<br />
CAUTION: When handling the plates, especially if you need to release them,<br />
be sure to wear protective gloves as the plate edges are sharp.<br />
The following are the most common plate loading failures:<br />
• Plate is stuck<br />
• Double Loading<br />
• Drum related errors<br />
• Punch is stuck<br />
The following are the most common error messages:<br />
• Error Message: Plate did not reach punch position<br />
• Error Message: Vacuum didn't grab plate<br />
• Error Message: Drum Fly-off<br />
• Error Message: Illegal plate size<br />
• Error Message: Illegal gripper width<br />
The following sections describe the actions that you should take when the<br />
above failures occur.<br />
Plates may get jammed inside the platesetter during plate loading. As<br />
explained in Loading Plates Manually on page 29, the message sent from<br />
the workstation to the PC Controller requests you to load a plate of<br />
specified size and thickness. If you load a plate with an incorrect height<br />
value, the plate will get jammed and cannot be properly loaded onto the<br />
drum. In this case, you will need to manually remove the jammed plate.<br />
Special precautions are required when performing this procedure.<br />
Note: Before removing a plate, remove objects or clothing that might get caught<br />
in the revolving drum or other moving parts, such as, ties and jewelry. Fold long<br />
sleeves and gather long hair.<br />
Note: Before removing a plate, switch off the main drum power switch on the<br />
Distribution box.
38 Chapter 4 – User Troubleshooting<br />
Note: The plate edges are sharp so the plate should not be handled with bare<br />
hands. Wear gloves before attempting to release the plate.<br />
Note: It is recommended to release the entire plate as one piece; do not<br />
attempt to cut the plate.<br />
Note: Released plates must be disposed; you may not re-use the plate.<br />
Note: Plate remnants left in the platesetter may cause mechanical and laser<br />
radiation hazards!<br />
When plate loading fails because of incorrect plate size, the Status<br />
indicator is Attention and the message window opens with the message<br />
“Illegal plate size”.<br />
To manually release the stuck plate:<br />
1. You first need to open the upper door from the main window: to<br />
interactively open the door, click on the rear door on the Machine<br />
online view. Alternatively, click Open Rear Door from Routine<br />
Functions menu.<br />
2. When the rear door is open, stand at the rear side of the platesetter<br />
and rotate the drum forward, towards the front of the platesetter.<br />
3. Rotate the drum until you can see the detached edge of the plate, that<br />
is, the edge that is not held by the tail grippers.<br />
4. Hold the detached edge of plate and gently pull it towards you until<br />
you can see the other edge of the plate, that is, the edge that is held by<br />
the head grippers.<br />
5. To release the plate from the head grippers: hold both sides of plate<br />
(left and right) and pull the plate abruptly towards you.
Plate Loading Failure 39<br />
6. Verify that the tail gripper did not move. If it did, then move it to the<br />
Preload position (0). To do this,<br />
a. Drag the tail gripper to the preload position (as shown in the<br />
picture below).<br />
b. In the Hardware dialog box, open the Loading system directory.
40 Chapter 4 – User Troubleshooting<br />
c. Double-click Loading system.<br />
d. In the Loading System dialog box, click Restart Plate State.<br />
e. Click Drum Init.<br />
f. Click Pre-load (in the same dialog box) to move the tail gripper to<br />
the correct position according to the defined plate size.<br />
The status indicator shows Ready (blue).<br />
7. Close the rear door.<br />
8. Close the loading system and hardware windows.<br />
9. Click the Reset button in the message window, and then Reset in the<br />
Confirm message that appears.<br />
Machine status is now Ready and you can proceed to loading the correct<br />
plate size.
Plate Loading Failure 41<br />
Double Loading<br />
Tip: Open the front door and look into the loading area in order to find out<br />
whether double loading has occurred.<br />
1. If the plates are in the cassette to punch area:<br />
• Gently try to push them back into the cassette.<br />
• If this is not possible, open the upper cover, remove the plates and<br />
place paper in between them and then place the plates back into<br />
the cassette.<br />
• In the Hardware window, select Loading System/Loading System<br />
to open the Loading System window.<br />
• In the window, click Restart Plate State.<br />
2. If plates are stuck halfway on the drum:<br />
• Open the rear door.<br />
• Then using your hands, slowly rotate the drum away from you<br />
(towards the cassette) until you can see the plate tail edge. (A<br />
metallic noise might be heard, which is caused by the edge being<br />
dragged on the roller system.)
42 Chapter 4 – User Troubleshooting<br />
3. If the plates are held by a tail gripper(s):<br />
Figure 16: Tail gripper<br />
• Release the gripper(s) from the plate.<br />
• Hold the edges of both plates and pull the plates towards you until<br />
the head gripper is visible.<br />
• Then, press on one or two head grippers while pulling the plates<br />
abruptly.<br />
• Completely remove the plates from the drum.<br />
• In the Hardware window, select Loading System/Loading System<br />
to open the Loading System window.<br />
• In the window, click Restart Plate State.<br />
• Move the gripper to Preload position (see Plate Geometry on<br />
page 30). Open the loading system and define a plate and press<br />
pre-load.<br />
4. Occasionally, a batch of plates may be problematic and a source for<br />
excessive static electricity. This may cause plate-loading problems.<br />
Tip: To minimize the probability of double loading, make sure the room<br />
temperature is maintained between 21 to 25 degrees, and humidity is<br />
approximately 55%.
Plate Loading Failure 43<br />
Punch is Stuck<br />
If the punch gets stuck while punching a plate, try the following:<br />
Figure 17: Punch system<br />
1. Remove the plate. If you cannot remove it, the punch pin may still be<br />
in its low position in the plate.
44 Chapter 4 – User Troubleshooting<br />
2. If this is the case, you need to release the punch:<br />
<br />
<br />
<br />
<br />
Make sure the doors are closed.<br />
In the Hardware window, select Punch System/Punch Motor/Punch<br />
Motor xx (where xx is the punch number) and Punch System/<br />
Detector/Punch Motor #Home Pos.Det.<br />
The punch numbers proceed from left to right.<br />
If you are not sure which punch needs to be released, open the front<br />
door and remove the plate and close the door. Then activate the<br />
punches one by one by clicking Start, to see which is the<br />
problematic punch. If the Home Position does not change to ON,<br />
then that is the problematic punch.<br />
If the plate is stuck and you cannot remove it, then activate the<br />
punches one by one by clicking Start, to see which is the<br />
problematic punch. If the Home Position does not change to ON,<br />
then that is the problematic punch.<br />
If you discover a problematic punch, contact your service representative.<br />
Drum Related Errors<br />
Plate loading fails with drum related error Drum did not reach<br />
position or Load Gripper is protected by Load Gripper<br />
Protector. There may be several causes to this error message. Check the<br />
following possibilities:<br />
1. Verify that all covers and panels are properly closed. Make sure that no<br />
interlock is active (that is, an interlock indicator does not appear on<br />
the main application window, and the machine status is not Service).<br />
2. Verify that the air compressor supply to the platesetter is adequate<br />
(minimum setting of the air compressor should be 6 Bar).<br />
3. From the Hardware window, select Loading System/Loading System.<br />
In the Loading System dialog box, click Drum Init.
Plate Loading Failure 45<br />
Error Message: Plate Did Not Reach Punch Position<br />
Plate loading fails with error message: Plate did not reach punch<br />
position.<br />
1. Verify that the plates are properly centered in the cassette (both side<br />
brackets touch the plate sides) and the rear bracket is approximately<br />
1 mm from plate edge.<br />
2. Check if the plate edge is bent, cut or coated with glue. This may cause<br />
the short pins to fail a plate reading when the pins are supposed to<br />
touch the plate (these are the centering system pins and/or the pins<br />
near the punch blocks). Try rotating the plate 180 degrees. This may<br />
help to verify if the plate edge is the cause of the problem.<br />
3. Look through the cassette entrance towards the punch block units.<br />
4. If you can see a punch pin in the middle of the punch slot, this means<br />
that a plate may get stuck on its way to the punch. In this case, contact<br />
your service representative.<br />

Error Message: Vacuum Did Not Grab Plate<br />
Plate loading fails with error message Vacuum did not grab plate.<br />
Open the front door and check the plate location. The cause and solution<br />
to this problem depends on plate location:<br />
1. Verify that the air compressor supply to the platesetter is adequate<br />
(minimum setting of the air compressor should be 6 Bar).<br />
2. Open the cassette door. If you can see the plate inside the cassette,<br />
verify that the plate edge is not under the two side brackets. In this<br />
case, the plate cannot be loaded. Try to reposition the plate in the<br />
cassette or add more plates into the cassette.<br />
Figure 19: Centering system<br />
3. Verify that the loading bar is horizontal to the plate (see below). Push<br />
the bar toward the drum until it touches the two vertical metal<br />
brackets. The loading bar should be parallel to the brackets on both<br />
axes. If it is not parallel, contact your service representative.
Plate Loading Failure 47<br />
Figure 20: XY Bar<br />
4. If the plate is partially out of the cassette, check that all the Vacuum<br />
suction cups on the XY bar are intact, complete and are not torn. If<br />
there is a problem with the suction cups, contact your service<br />
representative.<br />
5. If the plate is halfway onto the punch blocks, examine the front edge<br />
of the plate. If there are bends or dents in the plate, these may be as a<br />
result of the plate hitting one of the punch blocks as it is loaded from<br />
the cassette. Remove the plate and rotate it in the cassette.<br />
Error Message: Drum Fly-off<br />
1. Open the rear door, and manually remove the plate.<br />
2. Move all tail grippers to the end of their slots (near the head grippers).<br />
Make sure that the tail grippers are not moved beyond the head<br />
gripper holes.<br />
3. Verify that the load/unload rollers are in their proper position (they<br />
did not separate from the springs).<br />
4. Close the doors.<br />
5. From the Hardware window, select Loading System/Loading System,<br />
and click the following: Restart Plate State, Drum and New Plate.
48 Chapter 4 – User Troubleshooting<br />
6. Resend the job from the Brisque.<br />
Error Message: Illegal Plate Size<br />
Error Message: Illegal Gripper Width<br />
There may be several causes to this error message. Do the following:<br />
• Measure the plate in the cassette.<br />
• Verify that the plate size defined in the Off-line/Current Cassette dialog<br />
box is the plate size that was actually loaded into the cassette. Plate size<br />
should be within +/-1 mm of the dimensions defined in the Media<br />
Definition dialog box.<br />
• Clean the centering pins.<br />
• Check the plate edges where the centering pins touch, see if there are<br />
bumps, dents, dirt, glue etc... - this could prevent any electrical contact<br />
from occurring.<br />
There may be several causes to this error message. Check the following<br />
possibilities:<br />
1. Make sure no paper accompanied the plate to the centering system.<br />
2. Open the front door and manually remove the plate from the drum.<br />
For instructions, see Releasing Stuck Plates on page 37.<br />
3. Move all tail grippers to the end of their slots (near the head gripper).<br />
Make sure not to move them beyond the head gripper holes.<br />
4. Close the front door.<br />
5. From the Hardware window, select Loading System/Loading System.<br />
6. In the Loading System window that is displayed, click New Plate.<br />
7. Clean the two red LED sensors located on both sides of the drum<br />
chassis using a dry cloth (see below).
Plate Unloading Problems 49<br />
Figure 21: Side to side detector<br />
Plate Unloading Problems<br />
Plate Does Not Unload<br />
Plate unloading problems may be caused by one of the following:<br />
• Plate does not unload from the platesetter<br />
• Unload failure after plate restart<br />
1. Make sure that the previous plate entered the processor correctly.<br />
2. If it did not, this plate may be blocking the conveyor sensor. Verify<br />
that the processor is in Ready state, and clear any error message on the<br />
processor panel.<br />
3. If there is still a problem, contact the processor technician.<br />
4. Move the previous plate into the processor. Then, from the Routine<br />
Functions menu, click Unload Plate to manually unload the current<br />
plate.<br />
5. Check that there are no error messages relating to Vibration or Fly<br />
Off. If there are such messages, please contact your service<br />
representative.
50 Chapter 4 – User Troubleshooting<br />
6. Try to manually unload the plate. Then load and unload a different<br />
plate size. If this goes smoothly then there may be a specific problem<br />
with the original plate size.<br />
Figure 22: Unloading system<br />
7. Load the plate into the processor. Then examine the plate to see if it<br />
was partially exposed, or not exposed at all. If it was partially exposed,<br />
this can indicate a problem with the exposure sequence and not a<br />
plate-unloading problem.
Exposure Failure Problem 51<br />
Unload Failure After Plate Restart<br />
If you have a problem performing Restart Plate State while there is a plate<br />
on the drum, then you will not be able to expose the plate or unload it,<br />
because Restart Plate State resets the plate status to No plate on drum. To<br />
resolve this problem, click Force Plate On Drum to force the system to<br />
acknowledge the plate on the drum. Then, you can either expose the plate<br />
or unload it.<br />
Important: Never use Force Plate On Drum before performing a visual<br />
check that there is actually a plate on the drum.<br />
Exposure Failure Problem<br />
Exposure Does Not Start<br />
Exposure does not start at all and the error messages relates to the Host.<br />
There may be several causes to this error message.<br />
1. Verify the machine is ON and in Ready mode.<br />
Note: Make sure there is no error message on the PC Controller.<br />
2. On Brisque, go to Devices > Platesetter; select <strong>Lotem</strong> > <strong>Lotem</strong> <strong>400</strong>.<br />
3. Click the Reconfigure button.<br />
4. In the Queue Manager, a red blinking icon appears on the upper part<br />
of the dialog box indicating an error. From the Tools menu, select<br />
Operate Control > Plate Expose > <strong>Lotem</strong> <strong>400</strong>.<br />
5. Click OK.<br />
If the blinking icon disappears, then send another expose job. If not, in<br />
the In Queue area, select the problematic error message. Double-click<br />
it to receive an explanation of the problem.

Communication Problems with TSP Board<br />
1. Verify that the Data cable is securely connected to the workstation.<br />
2. Check that the Network or the Point-to-Point cable between the<br />
platesetter and the workstation is properly connected.<br />
3. Check if you can ping the platesetter from the workstation:<br />
• Open the terminal window on the workstation<br />
• On the PC, open Settings/Control Panel/Network/TCPIPP/<br />
Properties and type ping 192.9.200.2.<br />
To stop the ping sequence type: CTRL+C.
