■ Cassette Pickup Assembly (550-sheet 1st cassette model)
● Overview
The paper inside the cassette is held up by the lifter plate.
When pickup takes place, the pickup solenoid (SL1) is turned on, and the pickup roller is moved down. When the pickup roller
comes into contact with the surface of paper, the sheet is picked up by rotation of the roller.
Only a single sheet of paper picked up is moved to the feed path by the feed roller and the separation roller, and moved as far
as the registration roller by the pickup vertical path roller.
The pickup vertical path roller, pickup roller, feed roller, and separation roller are driven by the cassette pickup motor (M1).

● Paper Size Detection
Paper size of the cassette can be automatically detected by adjusting the position of the guide plate.
Concavo-convex area of the cassette dial is switched when the guide plate is shifted and two Size Switches on a printer are
switched. Length and width are detected according to the ON / OFF combination of switches. As long as standard paper, both
AB type and inch type can be used. However, size should be found manually on the check screen for the combination of A5-
Rand STMT-R or the combination of B5-R and EXEC.
