1.8 CLEANING SECTION

1. When servicing the cleaning section, be careful not to damage the edge
of the cleaning blade.
2. Do not touch the cleaning brush with bare hands.
3. Before disassembling the cleaning section, place a sheet of paper under
it to catch any toner falling from the section.
4. Empty the used toner collection bottle at every PM.
5. Apply setting powder to the new cleaning blade.

1.9 PRE-TRANSFER LAMP

1. After cleaning the pre-transfer lamp filter, rub it lightly with your finger to
discharge any static electricity on the filter.
1.10 PAPER FEED
1. Do not touch the pick-up, feed, separation rollers and the friction pads
with oily bare hands.
2. The side fences and the rear fence of the paper trays should be
positioned correctly to align with the actual paper size. Otherwise, paper
misfeeds may occur.
3. Be careful when reinstalling the paper feed (pick-up, feed, separation)
rollers in the paper tray unit. They are not interchangeable with the feed
rollers of the by-pass feed tray and 3.5 K LCT because the feeding
direction is different.
4. When actuating the front door safety switch to check the machine
operation while the front doors are open also actuate the lower front door
safety switch. Otherwise, the paper feed motor does not activate, causing
SC501.
1.11 FUSING UNIT
1. Be careful not to damage the edges of the hot roller strippers or their
tension springs.
2. Do not touch the fusing lamp with bare hands.
3. Make sure that the fusing lamp is positioned correctly (the yellow
connector must be at the rear) and that it does not touch the inner surface
of the hot roller.
