2.2.1 Paper Feed Mechanism

EPSON AcuLaser C2000 has 2 paper feed methods:
Tray 1 (150 sheets) + Tray 2 (500 sheets)

Optional 500 sheets cassette unit (Tray 3) is also available.

2.2.1.1 Tray 1

When the paper feed solenoid (SL 8) is turned ON, the driving power from the
transfer motor (M1) is transmitted to the paper feed roller via the paper feed
clutch (one-way clutch). Paper pushing plate is pushed to the paper feed roller,
and the paper feed roller rotates. The printer feeds the top sheet of paper.
Paper fed by the paper feed roller is carried to the timing roller via
transportation roller.

Separation pad method is used in order to separate each paper and
prevent feeding the second paper together.

If paper is OHP, it is detected by OHP sensor (PC11).

Paper empty switch (S9) detects if there is paper on Tray 1.

Tray 1 position sensor (PC15) detects if Tray 1 is pulled and the paper
pushing plate is ready to push paper to the paper feed roller.
