Recommendations for Cleaning the Printer

To clean the printer, do the following:

  1. Disable the host attachments. See Enabling and Disabling Attachments for details.
  2. Separate the forms at a perforation below the forms guide on the transfer station.
  3. Move the static brush to the left with your hand so that the forms fall back into the input area. Ensure that forms do not cover the end-of-forms sensor in the input area.
  4. Advance the forms by SELECTING the NPRO push-button on the Display/Touch Screen main window.

    The END OF FORMS 078A message appears on the Display/Touch Screen.

    Note:
    NPRO is not operable if the Thread/Align Forms procedure window appears.
  5. SELECT the NPRO push-button again.

    In duplex mode, the forms move through both Printer 1 and Printer 2 to either the stacker on Printer 2 or to a postprocessing device behind Printer 2. In simplex mode, the forms move through the printer to the stacker or to a postprocessing device behind the printer.

    If forms have moved to a printer stacker, go to step 6.

    If forms have moved to a postprocessing device, go to step 7.

  6. Unload the stacker. See Unloading the Stacker.

    Perform the Shutdown procedure.

  7. Switch off power to the printer. See Controlling the System Power for details.
    Attention!

    Damage to the printer can occur if you do not turn printer power off before you use the vacuum cleaner.

  8. Plug a toner-certified vacuum cleaner into an outlet near the printer.
    DEVELOPER AREA:

  9. Open the left top and front center left covers of the printer.
    This is an image that illustrates the positions of the three coronas that you need to clean.
  10. The printer has three coronas that you need to clean. The charge corona (1) and the pre-clean corona (2) are in the developer area; the transfer corona (3) is in the transfer station area.

    To clean the charge (1) and preclean (2) coronas, do the following:

    Important Note About the Coronas

    There is no device to prevent you from pulling out the corona wires. Be careful not to break the thin wires and tiny retractor springs inside the corona.

    This is an image that illustrates how to pull the charge corona and the preclean corona out of theirs tracks.
    1. Pull each white corona toward you until it is almost out of its track. A brush inside the corona housing cleans thecorona as you pull it out and then push it back in.
    2. Gently push each corona back into place. Ensure that you have pushed the corona in completely.
  11. Use a cloth or paper towel to wipe away any paper dust, toner, or other debris from the developer area.
  12. Close the front center right cover of the printer.
    Important

    The front center right cover must be completely closed whenever the printer is running. Light entering the printer can significantly reduce print quality.

    FORMS INPUT AREA:
    This is an image that illustrates the forms input area.
  13. Open the top left and front left center covers of the printer, if they are not already open.
  14. Use a toner-certified vacuum cleaner to clean the:
    TRANSFER STATION AREA:
    Attention!

    Use care when you clean behind the transfer station. Open the transfer station to its full upright position to ensure that the drum is completely covered.

    This is an image that illustrates the Caution 101 message.
  15. Open the upper tractor covers.
  16. Use a soft cloth to clean the upper tractor jam sensor (the glass window under the upper front tractor cover). If necessary, use a pencil eraser to remove forms residue.
  17. Use a vacuum cleaner to remove dust and debris around the upper tractor pins.
  18. Close the upper tractor covers.
  19. Clean the static discharge brush on the transfer station.

  21. Open the lower tractor covers.
  22. Vacuum the lower tractor pins to remove forms dust and debris.
  23. Close the lower tractor covers.
  24. To clean the transfer corona (3), do the following:
    Important Note About Cleaning the Coronas

    There is no device to prevent you from pulling out the coronas. Be careful not to break the thin wires and tiny retractor springs inside the corona assemblies.

    This is an image that illustrates how to clean the transfer corona.
    1. Gently pull the white corona toward you until it is almost out of its track. A brush inside the corona housing cleans the corona.
    2. Gently push the corona back into place. Ensure that you have pushed the corona in completely.
  25. Clean the brushes below the transfer station.
  26. Vacuum the paper dust from the area below the transfer station.
  27. Gently lower the transfer station toward the photoconductor drum and latch it using the Transfer Station Control Lever. See Transfer Station Control Lever and Tractor Control Levers for details.
  28. Close the top left and front center left covers of the printer.
    STACKER AREA:

    This is an image that illustrates the stacker area.
  29. Open the stacker gate (5) if the buffer/flipper unit or an installed postprocessing device does not interfere.
  30. Use a toner-certified vacuum cleaner to clean paper dust, chads, and other debris from the following:

    If you cannot open the stacker gate completely because of interference from the buffer/flipper unit or an installed postprocessing device, open the gate as wide as you can. Clean as much of the area as you can reach.

    This is an image that illustrates how to use a toner-certified vacuum cleaner to clean paper dust, chads, and other debris.
  31. Use a soft cloth to clean the six stacker jam sensors and two mirrors.
    This is an image that illustrates the positions of the six stacker jam sensors and two mirrors.
  32. Close the stacker gate.
    FUSER AREA:
  33. Open the front left cover.
  34. Use a soft cloth or paper towel to wipe up excess fuser oil on any surfaces.

    Important Note About Cleaners

    Do not use commercial cleaners that might contain ammonia, solvents, or other volatile chemicals. The vapors from these cleaners can cause chemical reactions that result in reduced print quality.

  44. Power on the printer. See Controlling the System Power.
  45. Load forms into the printer, if necessary. See Loading Forms (Simplex or Dual Simplex Mode) or Loading Forms (Duplex Mode) for details.

    This step is not required if you did not unload forms before starting this procedure.

  46. Enable the host attachments, if necessary. See Enabling and Disabling Attachments for details.
