Step Actions and Questions
5 Check for +24 V to the OPTFDR Board.
1. Disconnect P/J83.
2. Close the Interlock Switch while testing.
Is the voltage between P83-3 <=> P83-4 on the
Lower Feeder Circuit Board +24 V?
6 Check all pins on the OPFREC2 Harness
PL12.3.1 for continuity.
1. Disconnect P/J172 and P/J83.
2. Check continuity between J172 <=> P83.
7 Replace the Drive Assembly (page 8-121).
Does the error persist?
8 Check the Turn Roller.

10
Check for +24 V to the Turn Clutch.
1. Disconnect P/J825
2. Close the Interlock Switch while testing.
Is there +24 V across P85-2 <+>ground?
11 Check all pins on the OPFDR2 Harness
PL12.3.7 for continuity.
1. Disconnect P/J85 and P/J825.
2. Check continuity between J85 <=> P825.
12
Check Turn Clutch resistance.
Disconnect P/J825.
Is the resistance between J825-1 <=>
J825-2 less than 200Ω?
13
Check the Feed Gear.
Does the Feed Gear in the Paper Pick
Assembly turn when printing a sheet of paper?
14
Test the Feed Solenoid.
Run the Service Diagnostics Feed Solenoid
test.
