[E]

[D]

[C]

There are two types of paper t ray un it: one tray and three tray types. Each paper tray [A] is a drawer type and their function and mechanism are exactly the same as those of the main frame .

All the electrical components of the pape r tray are controlled by the copier main control board through the tray control board.

All the tray rollers are driven by the m ain fram e via the tr ay un it dr ive and driven gears [B,C]. When the tray unit drive clutch [D] is energ i zed, the drive is transmitted to the paper tray unit and the relay rollers start rotating. When the paper feed clutch [E] for the selected paper tray is energized, paper is fed from the paper tray to the ma in frame through the relay rollers.

5.1 SERVICE REMARKS

1. Do not touch the pick-up, feed, sepa r at i on roller s an d the friction pads with oily bare hands.

2. The side fences and the rear fen ce of t he pap er tr a ys shou ld be positioned correctly to align with the actual paper size. Otherwise, paper misfeeds may occur.

3. The friction pad should be replaced together with the friction pad holder and pad entrance seal as an assembly.

4. The friction pad assembly and the paper feed roller should be replaced as a set to maintain paper feed ability. (A worn out feed roller will provide incorrect friction pad pressure.)

5. The friction pad holder mounting bracket must be reinstalled on the original paper tray. Because the friction pad pressure is adjust ed for ea ch paper feed station independently at the factory.

6. The paper tray with the frictio n pad m ech an ism must be re inst alled at the original paper feeding statio n.

7. The friction pad pressure should not be adjusted in the field.
