2 Chapter 1 – Introduction
Lotem 400 Quantum Overview
The state-of-the-art Lotem 400® Quantum platesetter offers superb
quality and high platemaking productivity of up to 25 4-up plates per hour
(with MCU option). Creo SQUAREspot thermal imaging predictability and
consistency assures plate imaging integrity with Automatic loader. Driven
by a Brisque or Prinergy, the Lotem 400 Quantum is for the discriminating
printer who cannot compromise. This ultimate computer-to-plate (CTP)
device meets and adapts to all your needs for efficient, continuous
production that keeps the presses running.
Creo is a pioneer of thermal imaging, the de facto standard CTP
technology today due to its outstanding performance and quality.
SQUAREspot thermal imaging maintains consistent reliable plate imaging
despite normal process variation such as changes in plate sensitivity or
processor chemistry. This precise process control enables reliable FM
screening and artifact-free images.
Lotem 400 Quantum plate size ranges from 311 x 228 mm (12.25 x 9 inch)
to 622 x 750 mm (24.5 x 29.5 inch).
Available in the following configurations:
• Manual Loading
• Automatic Loading (See MCU for Lotem 400 User Guide,
653-00118A)
The fully automated platesetting sequence produces press-ready plates
without your intervention. Plates are loaded automatically from the
cassettes, after automatic slip-sheet removal. The customized, inline punch
system punches plates according to the press profile selected on the
workstation. Then plates are automatically mounted on the drum for
imaging and unloaded directly into an optional inline processor.

12 Chapter 2 – Lotem Controller User Interface
Overview
The Lotem Controller monitor is your interface with the Lotem 400
Quantum platesetter; it monitors the platesetter operation, is constantly
updated with the machine status and provides machine information. The
platesetter is controlled by the Lotem Controller located inside the
platesetter; the monitor resides on a nearby table, as shown in Typical
configuration at customer site on page 5. The job data is sent from the
Brisque or Prinergy, that is connected to the Lotem Controller (see
Communication & data flow between platesetter & workstation on page 7).
Figure 6: Lotem Controller monitor

User Interface 13
User Interface
The Lotem Controller monitor is your basic working area, where the
application indicators, buttons, popup menus and dialog boxes appear.
The workflow-oriented platesetter user interface is intuitively designed,
and minimal computer knowledge is required. The following features
support this design:
• Color-coded Status indicator indicates the machine status. For
example, if a problem occurs while you are away from the monitor
checking exposed plates, the problem indications on the screen are
visible from a distance.
• Large interface indicators can be seen from a distance, so you can be
alerted even when working away from the monitor.
• Monitor screen is divided into functional areas, as shown in the Main
window figure below.

Status Indicator
The Status indicator is fairly large and is color-coded for easy
identification. The indicator updates you on machine status even when
you are performing tasks away from the monitor. For example, you can
easily see when the Status indicator changes to Attention.
Start up (green) – machine is performing start up. All machine
components go to Home position.
Off-line (gray) – like Ready, but you cannot expose plates or run
calibration tests; all other functions are available. After Start up and Stop,
the machine automatically goes to Off-line. Click On-Line button on the
Routine Functions menu to set machine to Ready.
Ready (blue) – the machine is ready for operation and in On-Line mode;
you may load a plate and begin the expose job.
Working (green) – the machine is busy exposing the current job. While the
machine is working, you can place another plate on the Loading tray or
send additional jobs from the Brisque.
Attention (red) – the machine has stopped working and requires your
intervention, or has encountered a problem that requires servicing. An
appropriate message appears in the message section and normal operation
resumes only after the problem is solved.
Service (purple) – a door is open or a panel was removed (the Interlock
indicator appears on the Main window) or the machine is being serviced.
If a door is open, the Online machine view shows the open door.

Plate Geometry
This section describes aspects of the plate geometry and image section.
These aspects will help you plan for the plate exposure process and define
correct settings for your press and plate, and your image offset.
The figure below shows a negative working plate, where two strips of
emulsion remain – 10 mm at the head margin and 6 mm at the tail margin.
head margin
min 6 mm
max. plate size = 750 x 622

Figure 10: Negative working plate – various plate dimensions
Head margin – It defines the distance from the plate edge until the
beginning of the layout or the exposed image. This parameter is also
known as leading edge to print.
Tail margin – It defines the distance from the back edge of the plate to the
edge of the file or layout.
H (height) – plate height (around the drum).
W (width) – plate width (along the drum width).

Plate Geometry 27
In a negative exposure of a positive working plate, there is always an
emulsion area on the plate that is not exposed, therefore emulsion areas
remain. The size of these areas is determined as follows:
• At the head, the area is equal to the width of the plate and at a height of
up to 6 mm.
• At the tail, the area is equal to the width of the plate and at a height of
up to 6 mm.
For example, the image alignment in the Brisque is determined by the
Alignment, as defined in the Plate Expose window. For details, see Defining
the Plate Expose Parameters in the Brisque to Lotem 800 II / Lotem Quantum
Family Connectivity User Guide, 399Z1R762B.

Generic Troubleshooting Questions
There are several troubleshooting steps that you should complete before
calling the Response Center. These steps can prevent extensive down-time
by enabling you to solve problems independently. You will find these steps
are fully explained in the relevant troubleshooting document. Ideally, the
customer will have completed these steps before calling the Response
Center, and also reviewed the following questions and written the answers
down. If after completing these steps you find that the problem is not
resolved, please answer the following questions before calling the Response
Center. Write down your answers and have them available during your call.
The questions are as follows:
• When was the last time the machine worked properly?
• What was done since then? For example:
Was the machine moved?
Was the machine cleaned?
Was a new batch or type of plates used?
• Was an error message displayed on screen? If yes, what did it say
(include numbers, if any).
• What is the software version?
• Does the problem happen all the time (with all plates), or just some of
the time? For example:
With a particular plate brand, type and/or size?
Only when a few plates are left in the cassette?
• Does the problem seem to be a random occurrence?
• What are the temperature and humidity levels in the plate storage
room? For example:
Do they adhere to the plate manufacture’s guidelines? If not:
• In what ways?
• Does the temperature fluctuate radically?

Startup Problems 31
Startup Problems
PC Does Not Boot
Following are the most common start up problems:
• PC does not boot
• Windows does not start
• Windows does not launch
• Lotem application aborts
1. Verify that all power circuit breakers are in the ON position.
2. Verify that both on/off buttons at the rear of the platesetter (yellow
pushbuttons) are in the out position and lit.
3. Verify that the PC monitor power is ON.
Windows Does Not Launch
Windows does not launch and the error message relates to missing or
corrupted files.

following information should be supplied. This information is important
for addressing your problem.
• In case of an error in the PC Controller application, write down the
first five (5) error messages that are listed in the Message window of the
PC Controller main window.
• In case of error in the Brisque application, write down the Brisque
error number and message.
• In case of loading/unloading failure, write down the plate location, if
known.
• Write down the Brisque Job information (Job type, number of
separations, Screen set that is used and LW/CT resolution).
Plate Loading Failure
CAUTION: When handling the plates, especially if you need to release them,
be sure to wear protective gloves as the plate edges are sharp.
The following are the most common plate loading failures:
• Double loading
• Drum related errors
• Punch is stuck

Plate Loading Failure 33
The following are the most common error messages:
• Error Message: Plate did not reach punch position
• Error Message: Vacuum didn't grab plate
• Error Message: Drum Fly-off
• Error Message: Illegal plate size
• Error Message: Illegal gripper width
The following sections describe the actions that you should take when the
above failures occur.
Double Loading
Tip: Open the front door and look into the loading area in order to find out
whether double loading has occurred.
1. If the plates are in the cassette to punch area:
• Gently try to push them back into the cassette.
• If this is not possible, open the cassette door, remove the plates and
place paper in between them and then place the plates back into
the cassette.
• In the Hardware window, select Loading System/Loading System
to open the Loading System window.
• In the window, click Restart Plate State.
2. If plates are stuck halfway on the drum:
• Open the rear door.
• Then using your hands, slowly rotate the drum away from you
(towards the cassette) until you can see the plate tail edge. (A
metallic noise might be heard, which is caused by the edge being
dragged on the roller system.)

34 Chapter 4 – User Troubleshooting
3. If the plates are held by a tail gripper(s):
Figure 11: Tail gripper
• Release the gripper(s).
• Hold the edges of both plates and pull the plates towards you until
the head gripper is visible.
• Then, press on one or two head grippers while pulling the plates
abruptly.
• Completely remove the plates from the drum.
• In the Hardware window, select Loading System/Loading System
to open the Loading System window.
• In the window, click Restart Plate State.
• Open the loading system and define a plate and press pre-load.
4. Occasionally, a batch of plates may be problematic and a source for
excessive static electricity. This may cause plate-loading problems.
Tip: To minimize the probability of double loading, make sure the room
temperature is maintained between 21 to 25 degrees, and humidity is
approximately 55%.

Plate Loading Failure 35
Punch is Stuck
If the punch gets stuck while punching a plate, try the following:
Figure 12: Punch system
1. Remove the plate. If you cannot remove it, the punch pin may still be
in its low position in the plate.

36 Chapter 4 – User Troubleshooting
2. If this is the case, you need to release the punch: In the Hardware
window, select Punch System /Punch Motor /Punch Motor xx (where
xx is the punch number) and Punch System /Detector / Punch Motor
#Home Pos.Det. The punch numbers proceed from left to right. If you
are not sure which punch needs to be released, open the front door
and remove the plate and close the door. Then activate the punches
one by one by clicking Start, to see which is the problematic punch. If
the Home Position does not change to ON, then that is the
problematic punch.
If you discover a problematic punch, contact your service representative.
Drum Related Errors
Plate loading fails with drum related error Drum did not reach
position or Load Gripper is protected by Load Gripper
Protector. There may be several causes to this error message. Check the
following possibilities:
1. Verify that all covers and panels are properly closed. Make sure that no
interlock is active (that is, an interlock indicator does not appear on
the main application window, and the machine status is not Service).
2. Verify that the air compressor supply to the platesetter is adequate
(minimum setting of the air compressor should be 6 Bar).
3. From the Hardware window, select Loading System/Loading System.
In the Loading System dialog box, click Drum Init.
Error Message: Plate Did Not Reach Punch Position
Plate loading fails with error message: Plate did not reach punch
position.
1. Verify that the plates are properly centered in the cassette (both side
brackets touch the plate sides) and the rear bracket is approximately
1 mm from plate edge.
2. Check if the plate edge is bent, cut or coated with glue. This may cause
the short pins to fail a plate reading when the pins are supposed to
touch the plate (these are the centering system pins and/or the pins
near the punch blocks). Try rotating the plate 180 degrees. This may
help to verify if the plate edge is the cause of the problem.

Plate Loading Failure 37
3. Look through the cassette entrance towards the punch block units.
4. If you can see a punch pin in the middle of the punch slot, this means
that a plate may get stuck on its way to the punch. In this case, contact
your service representative.
Error Message: Vacuum Did Not Grab Plate
Plate loading fails with error message Vacuum did not grab plate.
Open the front door and check the plate location. The cause and solution
to this problem depends on plate location:
1. Verify that the air compressor supply to the platesetter is adequate
(minimum setting of the Air compressor should be 6 Bar).
2. Open the cassette door. If you can see the plate inside the cassette,
verify that the plate edge is not under the two side brackets. In this
case, the plate cannot be loaded. Try to reposition the plate in the
cassette.
Figure 13: Centering system

38 Chapter 4 – User Troubleshooting
3. Verify that the loading bar is horizontal to the plate (see below). Push
the bar toward the drum until it touches the two vertical metal
brackets. The loading bar should be parallel to the brackets on both
axes. If it is not parallel, contact your service representative.
Figure 14: XY Bar
4. If the plate is partially out of the cassette, check that all the Vacuum
suction cups on the XY bar are intact, complete and are not torn. If
there is a problem with the suction cups, contact your service
representative.
5. If the plate is halfway onto the punch blocks, examine the front edge
of the plate. If there are bends or dents in the plate, these may be as a
result of the plate hitting one of the punch blocks as it is loaded from
the cassette. Remove the plate and rotate it in the cassette.
Error Message: Drum Fly-off
1. Open the rear door, and manually remove the plate.
2. Move all tail grippers to the end of their slots (near the head grippers).
Make sure that the tail grippers are not moved beyond the head
gripper holes.
3. Close the doors.

Plate Loading Failure 39
4. From the Hardware window, select Loading System /Loading System,
and click the following: Restart Plate State, Drum and New Plate.
5. Resend the job from the Brisque.
Error Message: Illegal Plate Size
Error Message: Illegal Gripper Width
There may be several causes to this error message. Check the following:
• Measure the plate in the cassette. Verify that the plate size defined in
the Off-line/Current Cassette dialog box is the plate size that was
actually loaded into the cassette. Plate size should be within +/-1 mm
of the dimensions defined in the Media Definition dialog box.
There may be several causes to this error message. Check the following
possibilities:
1. Open the front door and manually remove the plate from the drum.
For instructions, see Double Loading on page 33.
2. Move all tail grippers to the end of their slots (near the head gripper).
Make sure not to move them beyond the head gripper holes.
3. Close the front door.
4. From the Hardware window, select Loading System/Loading System.
5. In the Loading System window that is displayed, click New Plate.
6. Clean the two red LED sensors located on both sides of the drum
chassis using a dry cloth (see below).

Figure 15: Side to side detector
Plate Unloading Problems
Plate Does Not Unload
Plate unloading problems may be caused by one of the following:
• Plate does not unload from the platesetter
• Unload failure after plate restart
1. Make sure that the previous plate entered the processor correctly.
2. If it did not, this plate may be blocking the conveyor sensor. Verify
that the processor is in Ready state, and clear any error message on the
processor panel.
3. If there is still a problem, contact the processor technician.
4. Move the previous plate into the processor. Then, from the Routine
Functions menu, click Unload Plate to manually unload the current
plate.
5. Check that there are no error messages relating to Vibration or Fly
Off. If there are such messages, please contact your service
representative.

Plate Unloading Problems 41
6. Try to manually unload the plate. Then load and unload a different
plate size. If this goes smoothly then there may be a specific problem
with the original plate size.
Figure 16: Unloading system
7. Load the plate into the processor. Then examine the plate to see if it
was partially exposed, or not exposed at all. If it was partially exposed,
this can indicate a problem with the exposure sequence and not a
plate-unloading problem.

42 Chapter 4 – User Troubleshooting
Unload Failure After Plate Restart
If you have a problem performing Restart Plate State while there is a plate
on the drum, then you will not be able to expose the plate or unload it,
because Restart Plate State resets the plate status to No plate on drum. To
resolve this problem, click Force Plate On Drum to force the system to
acknowledge the plate on the drum. Then, you can either expose the plate
or unload it.
Important: Never use Force Plate On Drum before performing a visual
check that there is actually a plate on the drum.
Exposure Failure Problem
Exposure Does Not Start
Exposure does not start at all and the error messages relates to the Host.
There may be several causes to this error message. Check the following
possibilities:
1. In the Platesetter Config window on the Brisque, verify that the Status
icon at the upper right corner displays Connected.
2. If Not Connected is displayed, verify that the Data cable or Fiber optic
is properly connected, and that the Brisque and PC Controller are on
the network (in some cases, a Point To Point connection exists).
3. To check the connection, ping the platesetter from the Brisque: open
the terminal window on the Brisque.
4. On the PC, open Settings /Control Panel /Network /TCPIP /Properties
and type ping 192.9.200.2.
Important: The Lotem IP may be a different number. You can verify the
number on the Brisque. Select SCISMITPlatesetter and then the Display Lotem
IP Address option in the Lotem IP address box.
5. To stop the ping sequence type: CTRL+C (check network connection as
shown).
6. Check that the proper Screen Set is used.
7. Try exposing a different file using a different setting.

Communication Problems with TSP Board 43
8. Verify that the platesetter is in Ready status and that the Brisque
queue is not suspended.
Communication Problems with TSP Board
1. Verify that the Data cable is securely connected to the Brisque.
2. Check that the Network or the Point-to-Point cable between the
platesetter and the Brisque is properly connected.
3. Check if you can ping the platesetter from the Brisque:
• Open the terminal window on the Brisque
• On the PC, open Settings /Control Panel /Network /TCPIP /
Properties and type ping 192.9.200.2.
Important: The Lotem IP may be a different number. You can verify the
number on the Brisque. Select SCISMITPlatesetter and then, in the Lotem IP
address box, the Display Lotem IP Address option.
To stop the ping sequence type: CTRL+C. .
