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 normal force 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 normal force
rollers, feed the 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.
Vacuuming inside the
scanner The sensors located under the horizontal plate in the feeder/horizontal
transport area and in the upper section of the lower roller housing
assembly, the exposure lamp housings, and the air filter should be
vacuumed or wiped down thoroughly with a clean, dry, soft, lint-free
cloth at least once a week.
Refer to the instructions and illustrations provided in the Chapter 7,
Troubleshooting,
to assist in accessing the sensor locations.

and/or damage to the machine.
6. Slide the lower roller housing assembly back into its original
position.
7. Replace the imaging guides.
8. Vacuum the screen located at the base of the transport system.
