Switch (Media Size) - Lexmark T650n Service Manual

4062-XXX

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 system card assembly.
Sensor (media empty)
If media runs out in a media tray assembly, the actuator lowers and the actuator flag, unlocks the sensing area
of the sensor (media empty). The sensor light is transmitted. When the sensing area is blocked (media is
present), the signal is off.
Sensor (media low)
This sensor detects by the actuator position whether media in the media tray assembly is low. When the flag of
the actuator blocks, then unblocks the sensing area of the sensor (media low), the media level is determined to
be low
Sensor (pass-thru)
A photointerrupter sensor with a built-in flag that sends a signal to the engine where the media from the input
tray passes. This will trigger the pick arm to pick the next media.
