4. OVERVIEW

This unit adds two additional universal cassettes (500 sheets each), which are the third and
fourth cassettes, to the copier.
Both the third and fourth paper feed stations have an FRR (Feed and reverse roller)
mechanism which is similar to the feed system of the copier, except for the following items.
1. Both third and fourth cassette bottom plates can be lowered mechanically to load paper
without removing the cassettes.
2. The pick-up, paper feed, and separation rollers are driven by the bank motor (an ac
motor) via the third and fourth paper feed clutches and gears.
The second and third relay rollers transport paper to the registration rollers of the copier. They
are driven by the bank motor. The second and third relay sensors monitor the paper feed
timing.
To facilitate loading paper and removing misfed paper, the following four mechanisms are
included in the bank.
1. Front Loading Mechanism
The paper supply unit can be pulled all the way out. This mechanism makes paper loading
and misfeed removal easy.
2. Right Cover
Misfed paper remaining in between the bank and copier can be removed by opening this
cover.
3. Slide Mechanism
When the LCT is installed on the right side of the bank, it is impossible to open the right
cover for misfeed removal. The slide mechanism, however, slides the paper supply unit to
the left (after pulling the paper supply unit all the way out) for removal of misfed paper.
4. Second Relay Roller Drive Mechanism
This mechanism allows you to manually rotate the second relay roller to remove the misfed
paper.
