1.8 CLEANING SECTION IN THE DRUM UNIT
1. When servicing the cleaning section, be careful not to damage the edge of
the cleaning blade.
2. Apply setting powder to the surface of the drum when installing a new
cleaning blade. Otherwise, the cleaning blade catches the drum, and both the
cleaning blade and the drum will be damaged.
1.9 ERASE LAMP/PTL/QUENCHING LAMP
1. Place a sheet of paper over the transfer belt unit when removing the erase
lamp, the pre-transfer lamp (PTL), or the quenching lamp. Doing so prevents
these lamps from damaging the transfer belt if they fall down by mistake.
1.10 PAPER FEED
1. Do not touch the pick-up, feed, separation rollers, or the friction pads with
bare hands.
2. The side fences and the rear fence of the paper trays should be positioned
correctly in alignment with the actual paper size. Otherwise, paper misfeeds
may occur.
3. When using by-pass feed while placing the original directly on the exposure
glass, be sure to lower the platen cover or document feeder before pressing
the Start key. For the first copy using by-pass feed, the copier scans full size.
If the platen cover is opened, a completely black image is developed on the
drum outside the copy paper size. This black image is transferred not to the
copy paper but to the transfer belt. The toner transferred to the transfer belt
cannot be cleaned off completely by the cleaning blade. This may cause the
back of the next sheet of copy paper to be dirty.
4. When using by-pass feed, stop pushing the sheets of copy paper at the
moment that the paper end indicator turns off. If you do not do so, all the
sheets of paper get under the feed roller, causing a jam.
5. A157, A159, and A160 only: For users who mainly use B size paper, change
the paper feed roller position to the B size paper position when paper jams or
non-feeds occur. (See Replacement and Adjustment - Section 6.5 Paper
Feed Roller Replacement for A157/A159/A160.) This remark also applies to
the A553 paper tray unit.
