Checking the fine filter

Do this task when you see the following message: 0799 CHECK FINE FILTER.

You must do this task immediately. You cannot delay it as you can for some Out of Supplies conditions.
  1. From the rear of the printer, open the cover as shown.
  2. Ensure that the filter flange is aligned in the guide and that the fine filter is firmly pressed against the back of the recessed filter area.
  3. Close the right rear cover of the printer.
  4. To resume processing, select Start on the printer operator panel or on the Main touchscreen panel.
    <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.
  5. If the CHECK FINE FILTER message appears again, repeat steps 2 through 4.

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