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 />

12 Chapter 2 – PC Controller User Interface<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 />

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.

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.

by enabling you to solve problems independently. You will find these steps<br />

are fully explained in the relevant troubleshooting document. Ideally, the<br />

customer will have completed these steps before calling the Response<br />

Center, and also reviewed the following questions and written the answers<br />

down. If after completing these steps you find that the problem is not<br />

resolved, please answer the following questions before calling the Response<br />

Center. Write down your answers and have them available during your call.<br />

The questions are as follows:<br />

• When was the last time the machine worked properly?<br />

• 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.


52 Chapter 4 – User Troubleshooting<br />

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.
