RAP 69 E5: OCT CVR Open / Please Close CVR

The Rear Cover Assembly is open.
Procedure
Open and close the OCT Rear Cover. The error code reappears.
Y N
Problem solved.
Open the OCT Rear Cover and check the Rear Cover Interlock Switch. The Rear Cover Inter-
lock Switch is in good condition and the actuator moves freely.
Y N
Replace the OCT Rear Cover Interlock Switch (REP 10.13).
Enter Diagnostics and select Component Test. Scroll to Sensor Input test and press Enter [4].
Actuate and deactuate the Rear Cover Interlock Switch. The number on the LCD increments
each time you press and release the actuator.
Y N
Switch the printer power off. Remove the OCT Front Cover (REP 10.4). Disconnect P/
J524 from the OCT PWB. Switch the printer power on. Measure the voltage between
P524 pin 1 and frame ground. The voltage is 3.2VDC.
Y N
Measure the voltage between P/J514 pin 6 and frame ground. The
3.2VDC.
Y N
Switch the printer power off. Remove the Left Side Cover (REP 1.1) and the
Print Engine Controller PWB Cover (REP 8.5). Measure the voltage between P/
J19 pin 11 and frame ground. The voltage is 3.2VDC.
Y N
Replace the Print Engine Controller PWB (REP 8.5).
Check for continuity between P/J19 pin 11 and P/J501 pin 3 and between P/
J504 pin 6 and P/J514 pin 6. There is continuity between both sets of pins.
Y N
Repair or replace the OCT Harness (PL 10.2) or the Duplex interface Har-
ness (PL 9.2).
Replace the Duplex Interface PWB (REP 8.3).
Replace the OCT PWB (REP 10.14).
Switch the printer power off. Reconnect P/J524 to the OCT PWB. Switch the printer power
on. Measure the voltage between P524 pin 1 and frame ground as you actuate and deac-
tuate the interlock switch. The voltage is 3.2VDC when the switch is deactuated and
0.0VDC when the switch is actuated.
Y N
Replace the OCT Rear Cover Interlock Switch (REP 10.13).
Replace the Print Engine Controller PWB (REP 8.5).
Replace the Print Engine Controller PWB (REP 8.5).

RAP 70 OCT Motor Assembly

Procedure
Switch the printer power off. Remove the HVPS Cover (REP 1.6). On the Duplex Interface
PWB, disconnect P/J506 and measure the voltage between J506 pin 1 and frame ground.
There is 24VDC between J506 pin 1 and frame ground.
Y N
Replace the LVPS (REP 8.6).
Switch the printer Power off. Reconnect P/J506. Remove the OCT Front Cover (REP 10.4).
Disconnect P/J514 on the OCT PWB. Measure the voltage between J514 pin 8 and frame
ground. There is 24VDC between J514 pin 8 and frame ground.
Y N
Switch the printer power off. Measure the resistance between P/J504 and P/J514 as fol-
lows:
• J504 - 1 and J514 - 1
• J504 - 2 and J514 - 2
• J504 - 3 and J514 - 3
• J504 - 4 and J514 - 4
• J504 - 5 No Connection
• J504 - 6 and J514 - 6
voltage is
• J504 - 7 and J514 - 7
• J504 - 8 and J514 - 8
• J504 - 9 and J514 - 9
There is continuity between each of the pins.
Y N
Repair or replace the STK-O-Harness Assembly (PL 10.2) and the SK-1 Harness
Assembly (PL 9.1).
Replace the Duplex Interface Harness PWB (REP 8.3).
Switch printer power off. Reconnect P/J515. On the OCT PWB, measure the voltage between
P/J517 pin 3 and frame ground and P/J517 pin 4 and frame ground. Both
24VDC.
Y N
Replace the OCT PWB (PL 10.2).
Replace the OCT Motor Assembly (PL 10.2).
