RAP 54 C3: Tray Out / Install Tray 2 (or Tray 3)

Tray 2, Tray 3.
Procedure
Remove and reinstall the paper Tray. Enter Diagnostics and Select Test Print. Run Test Print
from problem tray. The C3 error code still appears.
Y N
Problem solved.
Inspect the Paper Stack End Guide position in the tray. The End Guide is snug against the
paper stack.
Y N
Adjust the position of the End Guide.
Enter Diagnostics and select Component Test. Scroll to Tray 2 Size or Tray 3 Size. Press the
Enter Key (key 4). The paper size indicated on the LCD matches the paper size actually in
Tray 1.
Y N
Remove the paper tray. Scroll to Sensor Input test. One at a time, press and release each
of the size actuators for the problem tray. The number on the LCD increments each
time you press and release one of the actuators.
Y N
Go to RAP 37
Check the size cam on the left side of the paper tray. The cams are in good condition
(not broken) and rotate freely as the paper tray end guide is moved.
Y N
Replace Tray 1 (PL 2.1/ PL 2.2).
Remove the 500 Sheet Feeder Left Cover (REP 11.3). As you insert the paper tray, watch
the size actuators move depending on the setting of paper tray. See Table 1.

Enter Diagnostics and select Component Test. Scroll to Sensor Input test and press Enter.
Press and release the Pre-Registration Actuator. The number on the LCD increments each
time you press and release the actuator.
Y N
Switch the printer power off. Remove the 500 Sheet Feeder Left Cover (REP 11.3). Dis-
connect P/J133 from the Feeder PWB. Switch the printer power on. Measure the voltage
between P133 pin 7 and frame ground and between P133 pin 9 and frame ground. Both
readings are +3.2VDC.
Y N
Replace the Feeder PWB (REP 11.8).
Switch the printer power off. Reconnect P/J133. Switch the printer power on. Measure the
voltage between P/J133 pin 6 and frame ground as you actuate and deactuate the Pre-
Registration Sensor Actuator. The voltage is +3.2VDC when deactuated and 0.0VDC
when actuated.
Y N
Check for continuity between P/J133 and P/J13P and between P/J13P and P/J13C.
Repair or replace as necessary. If the harness checks good, replace the Pre-Regis-
tration Sensor (REP 11.22).
With paper in the tray and the tray inserted into the 500 Sheet Feeder. measure the volt-
age between P/J132 pin 7 and frame ground as you actuate and deactuate the Pre-Reg-
istration Sensor. The voltage is +2.76VDC when deactuated and 3.2VDC when actu-
ated.
Y N
Replace the Feeder PWB (REP 11.8).
Switch the printer power off. Remove the printer Left Side Cover (REP 1.1) and the Print
Engine Controller PWB Cover (REP 8.5). Switch the printer power on. Measure the volt-
age between P/J13 pin 7 and frame ground as you actuate and deactuate the Pre-Regis-
tration Sensor. The voltage is +2.76VDC when deactuated and 3.2VDC when actu-
ated.
Y N
Check for continuity between P/J132 and P/J131 and between P/J131 and P/J13.
Repair or replace as necessary.
