1.8.Paper Feed

Media Tray

The main motor drives the pickup roller after the pickup solenoid is energized, which engages the pickup roller clutch and feeds a sheet of paper. The paper is pushed to the paper feed roller, which overdrives the paper slightly causing a buckleto ensure the paper is aligned with the stationary registration roller.

While triggering the registration sensor notifying the CPU paper is ready to feed. The paper at this point is the same as manual feed.

Manual Feed

when paper is inserted, it activates the registration sensor. At the porter time, the CPU energizes the registration solenoid that allows the registration roller to rotate, feeding paper to the top sensor.
