Pickup/feed/delivery system
The pickup/feed/delivery system consists of several types of feed rollers and sensors. The ECU uses
two motors and two solenoids to drive the rollers. Three media-detection sensors detect media as it
passes through the device. If media does not reach or pass each sensor within a specified time period,
the ECU determines that a jam has occurred and alerts the formatter.
The following components work together to feed media through the device:
●
M1, main motor
●
M2, fuser motor
●
SL1, tray 1 pickup solenoid
●
SL2, tray 2 pickup solenoid
●
PS502, duplexer media-detection sensor
●
Output-bin-full sensor
●
PS901, top-of-page sensor
●
PS902, tray 1 media-detection sensor
●
PS903, media-width sensor
●
SR1, top output-bin delivery flag
●
SR2, fuser-delivery flag
