Cleaning the ADF
sensor
The ADF sensor detects paper in the ADF. Dust and small particles of
paper may build up on the sensor, causing the ADF not to lower after
the last page is fed. Cleaning the ADF sensor once a week (or as
needed) will reduce this problem.
1. Remove all paper from the ADF.
2. Clean the ADF sensor with a small cleaning brush.
Cleaning and
replacing the lamps
The scanner lamps should be cleaned monthly (or as needed) and
periodically may need to be replaced. Lamp replacement may be
required if the control panel displays one of the following messages:
• Check front lamps
• Check back lamps
• Low front lamp level
• Low back lamp level
See the section entitled, “Supplies and consumables” for information on
ordering additional lamps.
The simplex scanner has two, individual lamps, and the duplex scanner
has two pairs of individual lamps (front and back) — one pair per
camera. All lamps can be replaced through the side access panel while
the scanner transport cover is open.
NOTE: With duplex scanners, both the front and back lamps should be
replaced at the same time for the best reliability and image
quality.
1. Shut down the host PC.
2. Power off the scanner.
3. Open the scanner transport cover.
4. Open the side access panel.
CAUTION: The lamps may be very HOT. Be sure the bulbs are cool
before changing them.
