Switch the printer power off. Remove the 500 Sheet Feeder Left Cover (REP 11.3). Dis-
connect P/J133 on the Feeder PWB. Measure the resistance between pins 10 and 11 on
the disconnected plug. The resistance is approximately 90 ohms.

Disconnect P/J135 from the Feed Head Assembly. On the Feed Head Assembly,
measure the resistance between P135 pin 1 and pin 2. The resistance is approxi-
mately 90 ohms.

Replace the Tray 2 or 3 Feed Solenoid (REP 11.11).
Repair or replace the Feed Head Harness (P/J133 to P/J135) (PL 11.3).
Switch the printer power on. Measure the voltage between P/J133 pin 10 on the Feeder
PWB and frame ground. The voltage is +24VDC.
Y
N
Measure the voltage between P/J132 pin 3 and frame ground. The voltage is
+24VDC.
Y
N
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 voltage between P/J13 pin 3 and frame ground. The voltage is
+24VDC.
Y
N
Replace the Print Engine Controller PWB (REP 8.5).
Check the continuity of the Feeder Harnesses (P/J132 to P/J131 and P/J131 to
P/J13). Repair or replace as necessary (PL 11.3).
Replace the Feeder PWB (REP 11.8).
Switch the printer power off. Reconnect P/J133. Enter Diagnostics and select Component
Test. Scroll to Tray 2 Feed Sol or Tray 3 Feed Sol. Measure the voltage between P/J133
pin 11 and frame ground. Press the Enter key. The voltage drops from +24VDC to
0.0VDC.
Y
N
Measure the voltage between P/J132 pin 4 and frame ground. Press the Enter key.
The voltage changes from 0.0VDC to 3.2VDC.
Y
N
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 voltage between P/J13 pin 4 and frame ground. The voltage
changes from 0.0VDC to 3.2VDC.
Y
N
Replace the Print Engine Controller PWB (REP 8.5).
Check the continuity of the Feeder Harnesses (P/J132 to P/J131 and P/J131 to
P/J13). Repair or replace as necessary (PL 11.3).
Replace the Tray 2/3 Feeder PWB (REP 11.8).
Check for mechanical binding of the solenoid or a defective spring. If the problem persists,
replace the Tray 2/3 Feed Solenoid (REP 11.11).
Scroll to Main Motor and press Enter. The Tray 2/3 Feed Rolls will rotate one revolution and
feed a sheet of paper. Open and close the Top Cover to stop the Main Motor. Open the printer
and remove the sheet of paper. Scroll to Main Motor and press Enter. Scroll to Turn Roll Clutch
and press Enter. Scroll to Tray 2 Feed Sol or Tray 2 Feed Sol and press Enter. A sheet of
paper is fed from Tray 2/3 to the Registration Rolls.
