Controls

Paper inside a cassette is lifted up by the Lifter Plate.
The Lifter Plate is lifted up by rotating the Cassette 2 Lifter Motor (M104). When the Cassette 2 Pickup Roller comes into contact
with the paper surface, the Cassette 2 Pickup Motor (M102) rotates to pick up the surface layer paper, and the Cassette 2 Feed
Roller and Cassette 2 Separation Roller feed only 1 sheet of paper to the feed path. Then, it is moved to the Pre-registration
Roller by the rotation of the Cassette 2 Pullout Motor (M106).
The Cassette 2 Pickup Roller, Cassette 2 Feed Roller, and Cassette 2 Separation Roller are driven by the Cassette 2 Pickup
Motor (M102) while the Cassette 2 Vertical Path Roller is operated by the rotation of the Cassette 2 Pullout Motor (M106).

Paper Size Detection Control

The paper size in the cassette is automatically detected by the Cassette 2 Size Detection Switch after the position of the Guide
Plate is adjusted and the cassette is installed in the host machine.
By shifting the Guide Plate, concavo-convex area of the Cassette Size Dial is switched and the Cassette Size Switch at the printer
side is switched. The switch consists of 3 microswitches, and the length is detected in accordance with the combination of
ON/OFF (ON when the switch is pressed). Any standard size paper of AB, inch, or AK configuration can be used. However,
distinction between A5-R and STMT-R (*) should be made manually on the check screen. Distinction between EXEC-R and 16K-
R and between LTR-R and 16K-R is automatically made according to the country setting.
*: Whether to select A5-R or STMT-R can be registered in the user mode setting.
