Media Feed/Lift Motor; Sensor (Feed-Out) - Lexmark C93x Service Manual

5057-XXX

Media feed/lift motor

This motor is activated to feed media and to lift the bottom plate. When feeding media, it rotates forward to drive the
pick roll. When lifting the bottom plate, it rotates reversely to drive the tray module gears to lift the lift up shaft.
Switch (media size)
This switch (media size) sets the size of media supplied from each media tray assembly. A signal indicating the
media size is transmitted as a voltage to the printer engine card assembly.
Sensor (media out)
If media runs out in a media tray assembly, the actuator lowers and the actuator flag, unlocks the sensing area of
the sensor (media out). The sensor light is transmitted. When the sensing area is blocked (media is present), the
signal is off.
Sensor (media level)
This sensor detects by the actuator position whether media in the media tray assembly is lifted. When the flag of the
actuator unblocks the sensing area of the sensor (media level), the sensor detects that the media has been lifted.

Sensor (feed-out)

This sensor detects the media just after it is fed from the media feed unit. When the flag of the actuator unblocks the
sensing area of the sensor (feed-out), the sensor detects that the media is present. The sensor (feed-out) is also
used as a relay sensor along the media path up to the sensor (registration) in order for the engine to monitor media
location.
