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.

5-8 A-61092 September 1999

Replacement
procedures Replacement procedures should be performed on an as-needed basis.
Components that need periodic replacement include the air filter,
exposure lamps and the imaging guides.
Replacing the air filter The air filter should be replaced at least once a year, more often if
needed.
IMPORTANT:
Never operate the scanner without an air filter installed.
The imaging apparatus will quickly become
contaminated with dust and dirt, impairing image quality.
1. Remove the air filter cover by pressing in on the top of the cover to
release the catch.

Replacing the exposure
lamps The exposure system consists of four long-life fluorescent lamps.
There are two lamp housings; one upper and one lower. Each lamp
housing contains two lamps.
Change the lamps at least every 500 hours, when image quality
appears to be degrading (and standard maintenance procedures do not
improve the image quality), or when requested to do so by an operator
message. Always replace both lamps in a housing at the same time, or
exposures may appear inconsistent. Always use the recommended
lamps, or image quality may be unacceptable.
1. Turn the side panel switch off.
2. Open the right side access door.
3. Remove the imaging guides. (Refer to the section entitled,
“Replacing the imaging guides”.)
4. Grasp the tab at the end of the upper lamp housing and slide the
housing out of the track.

WARNING: Make sure the lamps are cool before attempting
to remove them from the lamp housing.

5. Carefully grasp the end of the lamp that is nearest the tab and lift it
out of the lamp housing socket. Free the other end of the lamp and
lift it out of the lamp housing. Remove the second lamp in the same
manner.
6. Dispose of or recycle the used lamps.
7. Install each lamp using the following sequence of steps:
•Face the clear, horizontal line of the new lamp toward the slot in
the bottom of the lamp housing.
•Insert one end of the lamp into the socket at the tab end of the
lamp housing. Insert the opposite end of the lamp into the other
socket.
WARNING: The exposure lamps are fragile. Never apply
pressure to the center of the lamp; press down
only on the ends of the lamp.
•Gently push down on each end of the lamp. Do not force the
lamp into place. The lamp should fit securely into the housing
and click into place.
NOTE: Improperly installed lamps (i.e., not securely seated in
the lamp housing) will result in repeated low lamp
warnings.
8. Place the upper lamp housing in the track and slide it back into
place. Repeat Steps 4 through 8 to replace the lamps in the lower
lamp housing.
