Theory of Operation 2-35
■ Duplex Roller
Driven by the Duplex Motor, the Duplex Roller feeds the print media returned
from the Exit Roller to the Turn and Retard Rollers.
■ Feed Roller
When the Tray 1 (MPT) Feed Solenoid energizes, the Gear MPT and Idler gear
are engaged. The Feed Roller rotates feeding paper from Tray 1. After rotating
one turn, the Gear MPT and the Idler gear disengage, and the Feed Roller stops,
allowing only one sheet of paper to be fed through at a time.
■ Tray 1 (MPT) No Paper Sensor
Detects whether print media is present.
■ Tray 1 Feed Solenoid
Controls the operation (rotation/stop) of the Tray 1 (MPT) Feed Roller.
■ Exit Roller
Driven by the Duplex Motor, the Exit Roller moves the fused print media
partially into the output tray where it then reverses in duplex mode and feeds the
print media (fused on one side) in the direction of the Registration Chute.
