Paper Empty Detection

Sensor (PE1) drops into the cutout in the Paper Tray. This activates the Paper
Empty Sensor and the printer detects that the Multi-purpose Tray has run out of
paper.
3-2-2. Second Paper Cassette Unit (option)
Mechanism
- Since a drive motor is not installed in this unit, the drive of M1 is transmitted
to the paper take-up and transport sections in the unit via the Drive
Transmission Gear.
- Although the feeding method is the same as the Multi-purpose Tray in the
printer, the corner separation system is applied in this unit as the paper
separating method.
- Paper is separated at the corner by the paper separation claw in the paper
cassette and the strength of paper itself (corner separation system). One
sheet of paper is fed for each paper feed cycle.
- The Paper Take-up Solenoid (SL21) in the unit is controlled by the printer via
PWB-A in the unit.
