Diagnostic aids 3-65Switch (media size)This switch (media size) sets the size of media supplied from each media tray assembly. A signal indicating themedia 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 areaof the sensor (media empty). The sensor light is transmitted. When the sensing area is blocked (media ispresent), 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 ofthe actuator blocks, then unblocks the sensing area of the sensor (media low), the media level is determined tobe low.Multi-purpose feeder (MPF)The MPF is a mechanical unit supplying media to the printer. The driving force from the main drive motor drivemotor is transmitted to the MPF pick roll to feed media.MPF feed rollThe MPF pick roll feeds the media set on the MPF into the printer.MPF pick solenoidThe MPF pick solenoid transmits the driving force from the main drive motor assembly to the MPF pick roll.Sensor (MPF media empty)The sensor (MPF media out) detects whether media is present on the MPF.MPF pick solenoidMPF pick roll assemblySensor (MPF media empty)
