Possible Cause

Possible Solution

Small strips or pieces of paper are caught in the printer from the previous paper jam.

Remove small pieces of paper from the printer.

 

Prints not cut correctly

Possible Cause

Possible Solution

Strips of paper are caught in the knife area.

Remove the strips of paper from the knife area.

 

Print borders not the right size

Possible Cause

Possible Solution

The slug width is not correctly set.

Reset the slug width.
See Operator's Guide for more info.

The host software's image positioning is not correct.

Refer to the host software instructions.

The page start parameter may be incorrect.

See the Operator Guide for more info.

 

Print edge damaged and image is skewed

Possible Cause

Possible Solution

  • Paper not loaded correctly in paper cassette

  • Paper cassette clamp not secured correctly

  • Paper cassette not aligned with the pin when installed on the shelf

  • Paper cassette not picked up or carried correctly causing the paper to slide to one end ("telescope")

  1. Reload the paper in the paper cassette.

  2. Position the paper cassette on the shelf pin.

  3. Close the cassette clamp to lock the paper cassette into position.

    Note: Always carry the paper cassette with two hands to prevent the paper from telescoping.

  4. When loading paper into the printer:

    • cut the paper lead edge corners at a 45° angle.

    • wait for a message to feed

    • push the paper slowly into the printer rollers, keeping the paper taut between the cassette and the rollers.

      Note: Push the paper evenly so it remains flat and does not buckle. Do not push the paper too hard against the paper alignment guide.


 

Host computer and printer not communicating

Possible Cause

Possible Solution

The SCSI cable has been disturbed.

  1. Turn off the host computer and other SCSI devices.

  2. Turn off the printer.

  3. Disconnect the SCSI cable.

  4. Reconnect the SCSI cable.

  5. Power up the printer and wait for it to initialize.

  6. Power up the other devices.

  7. Power up the host computer.

 

Host computer does not recognize the printer

Possible Cause

Possible Solution

  • Clean the processor racks and socks.

  • Check that the crossover assemblies are installed correctly.

 

Chemistry build-up on printer exit rollers

Possible Cause

Possible Solution

  • Wet prints were pulled into the printer to clear a paper jam (often following Errors 65 or 260).

  • Splash guard was not used when performing processor maintenance.

  • Clean the rollers with a damp cloth.

  • Clear the paper jam.

  • Use the splash guard when performing processor maintenance.

 

Chemistry leaks from processor

Possible Cause

Possible Solution

Hose clamps or compression fittings are loose.

Tighten the clamps and compression fittings.

 

Text on the paper has flare

Possible Cause

Possible Solution

  • The text density is too high.

  • The processor is not in control.

  • The printer is not calibrated correctly.

  • Reduce the text density by driving the processor to the upper end of the control limits.

  • Calibrate the printer.

  • Download the latest calibration software and calibrate the printer. (Download here)

 

Supply or takeup door will not close

Possible Cause

Possible Solution

The door was closed with too much force, pushing the door latch in so it is flush with the door.

Use scissors to pull the latch back to its normal position. Close the door with a normal amount of force.

 

Printer icon disappeared (RP 50 LED Printer only)

If your Macintosh or Windows based computer crashes unexpectedly, the files can corrupt and the printer ICON or printer button can be deleted. This also happens if you press [Ctrl] [Alt] [Delete] on a Windows based computer, or [Ctrl] [Apple] [Power Key] on a Macintosh computer

The printer folder still exists but the system cannot access it. You must create a New Device.

 

Additional Troubleshooting Tips (Printer)

  • Check that the processor is turned ON and warmed up prior to printing.

  • Turn on the processor drive for 30 minutes before printing.

  • Correctly load, seat, and thread the paper into the paper cassettes.

  • Correctly close all doors prior to printing. If doors are ajar or if interlock switches are not closed, the printer will not print.

  • The error "sheet detected in sheet xport" may appear after reinitializing the printer if the printer was in the process of sending paper into the processor. If this occurs, wait until the sheet has been fully fed into the processor and then reinitialize the printer again.

  • If the printer indicates that it is reinitializing after an error occurs and you have not opened a door (but you do not hear the normal sounds of reinitialization for up to 2 minutes), the printer may be waiting for the sheet to go into the processor before attempting to reinitialize. Do not attempt to reinitialize the printer again.

  • Before connecting or disconnecting the SCSI cable or terminator, turn off the power to the printer and host computer. Also, if you replace the SCSI cable, remove the Ferrite bead from the existing SCSI cable and install it on the new SCSI cable.

 

Additional Troubleshooting Tips (Processor)

Follow these guidelines to avoid many error conditions:

  • Check that the processor is powered on and warmed up prior to printing.

  • Follow the daily, weekly, monthly, and periodic maintenance guidelines outlined in the Operator's Guide.

  • When adding chemicals or water to the processor tanks, install a splash guard over the processor entrance area to prevent water and chemicals from entering the printer.

  • Do not allow the emulsion side of processed prints to touch each other until they are completely dry.

Warning: When troubleshooting or performing maintenance procedures that require the main power to be turned off, turn off the main power for the processor on the OCP and at the circuit breaker to prevent:

  • injury from moving parts and high voltage electricity

  • losing the processor parameters.
