1) General descriptions
To realize the compact design, the front loading system and the fol-
dable multi paper feed unit (Option for some areas) are employed.
250 sheets
The paper feed tray is of the universal type and has capacity of 250
sheets. The front loading system allows the tray to be loaded from the
lower side of the front cabinet.
Manual paper feed is made in the multi paper feed.

2) Basic operations
(Tray paper feed operation)
When the CPFC (Cassette paper feed clutch) turn on, the paper feed
roller shaft, the paper feed roller, and the take-up roller rotate in the
direction of A. At the same time, the limiter spring moves down the
roller release arm. As a result, the take-up roller falls by its own
weight onto the paper surface, starting paper feed.
When the CPFC turns off, rotation stops and the take-up roller is
pushed up to the original position by the roller release arm spring.
(Manual paper feed operation)
There is no special mechanism for manual paper feed other than the
manual feed paper sensing actuator and the paper guide.
When the CPFC turns off, rotation stops and the take-up roller is
pushed up to the original position.
