Cleaning the paper path NOTE: Before doing the following procedure, clean the machine
thoroughly and use the roller cleaning pads to clean the feed,
separator and NFR rollers — start with a clean machine.
Use the Paper Path Cleaner to clean the paper path rollers.
Periodically feed a cleaning sheet with the gum side up through the
machine in both the portrait and landscape orientation.
The paper path should be cleaned twice a day. Before you clean the
paper path, be sure the feed and separator rollers and imaging guides
have been cleaned.
1. To ensure complete coverage of the transport and NFR rollers,
feed a cleaning sheet in the center, and to the left and right of the
feeder document guides.
2. Repeat the procedure until no further residue is picked up by the
cleaning sheet.
3. Using a clean Paper Path Cleaner sheet, repeat Step 1 to verify
that the rollers are clean.
4. Turn the gum side down, and repeat Steps 1 through 3.
NOTE: When the gum side is down, it may be necessary to hold
down the gap release lever to allow the Paper Path
Cleaner sheet to feed past the separator roller.
Regular use of Paper Path Cleaner sheets may result in fewer major
cleanings with the roller cleaning pads.
NOTE: If there are feeder errors after cleaning the feed and
separator rollers, refer to the section entitled, “Adjusting the
feed and separator roller gap” in Chapter 2.
