Pickup/Feed System
■Overview
Papers in the cassette are lifted up with the Lifter Plate.
At pickup, the Pickup Roller picks up a paper by coming down and contact with paper surface.
The Pickup Roller comes down when the Pickup Solenoide turns ON.
A paper picked up by the Pickup Roller is fed to the feed path with the Separation Roller, and
then, is fed to the Registration Roller with the Vertical Path Roller.
The Vertical Path Roller, Pickup Roller, Feed Roller and Separation Roller are driven by the
Cassette Pickup Motor.

■Paper Size Detection
At the cassette pickup assembly, since the feed speed is increased, detection cannot catch
up with it. Thus, delay and stationary jam detection are not executed at the Cassette 1 Pre-
Registration Sensor. Instead of it, the Vertical Path Sensor executes the delay and stationary
jam detection. Since the residual jam should be detected on each cassette, the Cassette 1
Pre-Registration Sensor detects it. Because the Vertical Path Sensor is too close and it is
unnecessary to execute detection, the Vertical Path Sensor does not execute residual jam
detection.

Also, the cassette presence is detected when the size switch is pushed. (If no switch is
pushed, it is determined as no cassette.))
●Separation paper list
It is recommended to separate the following paper depending on the paper status (especially
moisture absorption) and paper trimming state when setting the paper.
This “separation” can avoid troubles.

●Cassette Heater Control
This heater is controlled to keep constant internal temperature. Basically, when the
Environment Switch is ON, the heater is ON regardless of ON/OFF of the main power except
for during printing. (Excluding the case where the internal temperature is high)
