11. PAPER FEED AND REGISTRATION
11.1 OVERVIEW
This model has three paper feed stations: the large capacity tray feed station
(LCT machines only), the upper paper tray feed station (non-duplex
machines only) and the lower paper tray feed station.
The LCT holds 1000 sheets of paper. The upper and lower paper trays are
drawer trays that hold either 500 sheets of paper (A153/A155/A156 copiers)
or 250 sheets of paper (A157/A159/A160 copiers).
Paper can also be fed using the by-pass feed table, which uses the feed
mechanism of the LCT feed station. The by-pass feed table can hold 40
sheets of paper.
There are two types of paper feed system: the FRR feed system and the
corner separation system.
• The FRR feed system is used for the A153/A155/A156 copiers, the LCT
and the by-pass feed station.
• The corner separation system is used for the A157/A159/A160 copiers.
The top sheet of paper separates from the stack and is fed to the relay
rollers, then to the registration rollers.
There are two relay sensors, one located just under each set of relay rollers.
These sensors are used for paper jam detection.
