Perform DC330 Component Control on
page 2-26 to check the operation of the Turn
Roller Clutch:
• Tray 2 [071-026]
• Tray 3 [071-027]
• Tray 4 [071-028]
Is the Feed Roller Clutch operating properly?
Replace the MCU PWB
(REP 12.4 MCU PWB
on page 4-206).
Go to step 2.
2. Check the connection between the Feed Roller
Clutch and Feeder PWB.
Are the connectors P/J220 and P/J421 connected
securely?
Go to step 3. Connect the
connectors P/J220 and
P/J421.
3. Check the conductivity between the Feed Roller
Clutch and Feeder PWB.
Is the connection between P/J220 <=> P/J421
conducting properly?
Go to step 4. Replace the Option
Rear Feeder Harness
Assembly.
4. Check the resistance of the Turn Roller Clutch
Turn Off the power, remove the Turn Roller Clutch
(REP 15.18 Turn Roller Clutch on page 4-280),
and check the wire resistance between the two
terminals.
Is the resistance approximately 144 Ohms (at
68° F)?
Go to step 5. Replace the Turn Roller
