1.10 PAPER FEED
1. Do not touch the feed and relay rollers with oily hands.
2. A worn out registration roller can crease paper. Worn rollers should be
replaced.
3. The side fences and the end fence of the paper tray should be positioned
correctly so that they securely hold the paper. Otherwise, paper misfeeds
may occur.
1.11 DOCUMENT FEEDER
1. When installing or removing the document feeder, make sure that the
document feeder is in the open position.
2. A build-up of static electricity on the exposure glass can cause originals
to misfeed. Apply a small amount of silicon oil to the glass using a clean
cloth lightly dampened with silicon oil. This will reduce the amount of
friction.
1.12 OTHERS
1. When replacing the main board, remove the RAM pack from the old main
board and place it on the new main board. Then install the new main
board in the copier.
2. After installing a new main board with a new RAM pack, the Clear All
Memory (SP99) procedure (see page 4-10) must be performed. (Do not
perform SP99 if you have placed the old RAM pack on the new main
board.)
3. Never perform SP99 (Clear All Memory) except for the following two
cases:
a) When the copier malfunctions due to a damaged RAM pack.
b) When replacing the RAM pack.
4. Whenever SP99 (Clear All Memory) is performed, all the steps of the
procedure must be followed. Otherwise, copy quality might be seriously
affected.
5. When replacing a sensor, do not overtighten the screws. This may
damage the sensor.
6. If a customer reports that red image areas on the original do not appear
on the copy, instruct the customer to select the desired image density by
the Manual Image Density keys.
