Changing the fine filter

Figure 106. Fine filter
Fine filter

Do this task when you see the following message: 0791 CHANGE FINE FILTER.

Notes:
  1. You do not have to replace the fine filter the first time you see the CHANGE FINE FILTER message. To bypass the message, select Start on the printer operator panel or the Main touchscreen panel.

    The CHANGE FINE FILTER message reappears each time end-of-forms is reached, an error condition occurs, or every 4 000 feet of forms thereafter if you are using a roll-feed preprocessing device. When certain additional feet of forms have been processed since the message originally appeared, you must change the fine filter before you can return the printer to Ready status.

  2. To clear this message, the printer power must be on while you replace the fine filter.

You need the following items when you change the fine filter:

  1. From the rear of the printer, open the cover as shown.
  2. Locate the latch (1) on the left side of the fine filter. Squeeze the latch together and then firmly push the latch to the left until it snaps into place.
  3. Slowly pull out the old fine filter from the recessed filter area.
  4. Remove the plastic bag from the new fine filter and place the fine filter on the floor.
  5. Place the used fine filter into the plastic bag.
  6. Discard the used fine filter.
  7. Wipe the filter housing with a soft cloth to remove any debris.
  8. Firmly push the new fine filter all the way to the back of the housing. The latch you pressed to the left during filter removal must snap back to the right.
  9. Close the right rear cover of the printer.
  10. To resume processing, select Start on the printer operator panel or the Main touchscreen panel.
    CAUTION:
    <85>For printers with microcode levels, version 11.6.128 and higher, both printers and attached pre and postprocessing equipment can be started from the main panel of the printer console and the printer operator panels. Visually assure that no other personnel are working on the system before starting the system.
  11. If the CHECK FINE FILTER message appears, the fine filter is not pushed all the way to the back of the filter housing. Adjust the fine filter, and then repeat step 10.

    If that does not correct the problem, contact your service representative. See Service call procedure for instructions.
