Pickup/feed/delivery system
The pickup/feed/delivery system consists of several types of feed rollers and sensors. A motor and
solenoid are used to drive the rollers. Three media-detection sensors detect media as it passes through
the printer. If media does not reach or pass each sensor within a specified time period, the formatter
determines that a jam has occurred.
The following components are identified in
Figure 4-8 Pickup/feed/delivery system on page 58:
●
M1, main motor
●
SL1, pickup solenoid
●
PS751, top-of-page sensor
●
PS915, fuser-delivery sensor and duplex sensor
NOTE: This sensor has two sensor flags; one flag detects the media when it is delivered from
the fuser, and the other flag detects the media when it is reversed for duplexing.
●
PS702, media-width sensor
