RAP 37 Size Switch
Procedure
The problem is with a 2000 Sheet Feeder
Y
N
Remove the tray from the problem feeder. Inspect the Size Cams on the left side of the
paper tray. The Size Cams are intact and in good condition (no broken surfaces).
Y
N
Replace the paper tray (PL 2.1/ PL 2.2).
Visually inspect the Size Switch Actuators. The actuators move smoothly and are in
good condition (not broken or damaged).
Y
N
Replace the Left Guide Assembly (REP 3.6()REP 11.14).
Enter Diagnostics and select Component Test. Scroll to Sensor Input test and press
Enter. One at a time, press and release each of the size actuators. The number on the
LCD increments each time you press and release one of the actuators.
Y
N
The problem is with Tray 1 Size Sensor.
Y
N
Switch the printer power off. Remove the Left Cover from the 500 Sheet Feeder
(REP 11.3). Disconnect P/J138 from the Feeder PWB. Check the continuity
between the following pins, of the disconnected plug, while pressing the
switches:
•
P138-1 and P138-3 when pressing SW1 Bottom
•
P138-2 and P138-3 when pressing SW2
•
P138-4 and P138-3 when pressing SW3
•
P138-5 and P138-3 when pressing SW4 Top
There is continuity in each case.
Y
N
Check for pin to pin continuity of the Size Sensor Harness. Repair or
replace as necessary. If the harness is OK, replace the Size Sensor
Switch (PL 3.1).
Reconnect P/J138 to the feeder PWB. Switch the printer power on. Measure
the following voltages on P/J132 pin 5 as you actuate the switches (see Table
1).
All voltages are correct.
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 voltages on P/J13 pin 5 as you actuate the switches (see Table 1).
All voltages are correct.
Y
N
Check for continuity between P/J13 pin 5 (Print Engine Controller PWB)
and P/J131 pin 5 and between P/J131 pin 5 and P/J132 pin 5 (Feeder
PWB). (P/J131 is the connector between the printer and the 500 sheet
feeder). Repair or replace the harness as necessary.
Replace the Print Engine Controller PWB (REP 8.5).
Switch the printer power off. Remove the Left Side Cover (REP 1.1) from the printer.
Disconnect P/J20 from the Print Engine Controller PWB. Check the continuity
between the following pins, of the disconnected plug, while pressing the switches:
•
P20-7 and P138-3 when pressing SW1 Bottom
•
P20-6 and P138-3 when pressing SW2
•
P20-4 and P138-3 when pressing SW3
•
P20-3 and P138-3 when pressing SW4 Top
There is continuity in each case.
Y
N
Check for pin to pin continuity of the Size Sensor Harness. Repair or replace as
necessary. If the harness is OK, replace the Size Sensor Switch (PL 3.1).
Replace the Print Engine Controller PWB (REP 8.5).
The size sensors appear to be working correctly. If the problem persists, replace the Print
Engine Controller PWB (REP 8.5).
Enter Diagnostics and select Component Test. Scroll to Sensor Input test and press Enter [4].
Press and release the 2000 Sheet Feeder A4 Paper Sensor. The number on the LCD incre-
ments each time you press and release the sensor actuator.
Y
N
Switch the printer power off. Disconnect P/J604 from the 2000 Sheet Feeder PWB. Check
the resistance between pins 5 and 6 as you actuate and deactuate the Paper Size Sen-
sor. The resistance is zero when the sensor is actuated and infinite when deactu-
ated.
Y
N
Replace the 2000 Sheet Feeder A4 Paper Sensor (PL 12.2).
Replace the 2000 Sheet Feeder PWB (REP 12.10).
Replace the Print Engine Controller PWB (REP 8.5).
