Tray pick and lift drive
1 Lift plate
2 Pick roller
3 Sensor (pick position)
4 Motor (pick/lift)
5 Separator pad
6 Sensor (paper present)
Paper is lifted by the lift plate until the sensor (pick position) is triggered. The motor (pick/lift) starts, and then
enables the pick roller to feed the paper into the printer.
Note: The motor (pick/lift) also drives the lift plate when rotating in reverse.
To avoid multi‑sheet picking, the friction from the separator pad prevents the extra paper from entering the
printer.
The sensor (paper present) detects if the tray is empty.
