2.4 PAPER GATE CONTROL
Solenoid and Lever
The paper gate solenoid [C] controls
the motion of the lever [B]. The spring
[A] lifts the lever when the solenoid is
de-energized (off). The solenoid pulls
down the lever when the solenoid is
energized (on). When the solenoid is
energized, the front end of the lever
[D] positions the paper gate in the
printer for duplexing.
Paper Path
The table below lists the status and positions of the related components and their
available paper paths.
Solenoid Lever Paper Path
Off Up
Fusing unit → Exit tray
On Down
Fusing unit → Duplex unit
Possible Paper Jam
If the paper gate solenoid does not energize during duplex printing, these
symptoms can occur:
• The paper moves to the exit tray of the printer.
• Though the paper is not caught in the printer or in the duplex unit, the message
"Remove Misfeed Duplex Unit" is displayed.
NOTE: When the printer continuously outputs two or more sheets, the subsequent
sheet can be near the registration roller of the printer.
If the paper gate solenoid does not de-energize during duplex printing, these
symptoms can occur:
• The first-side image is correctly printed.
• The paper is moved correctly to the duplex unit.
• The paper stays in the fusing unit after the second-side image is printed.
