Paper never picks
Paper occasionally mispicks or picks multiple sheets at once
FRU Action
Paper pick assembly Open the left cover, and verify the solenoid and clutch are functioning when an
attempt is made to feed the paper.
• If the shaft of the assembly rotates and paper does not move, remove the
picking assembly and inspect the pick roll and pad. Replace the assembly if
necessary.
• If the shaft does not rotate, observe the solenoid when a paper pick is
requested. If the solenoid does not function, do the following:
With the printer off, disconnect the solenoid at J10 on the controller card.
Turn the printer on and verify +24 V dc on pin 1 of the card connector.
- If the voltage fails, check the controller card. See “Controller card
service check” on page 2-24.
- If the voltage is correct, replace the paper pick assembly. See “Paper
pick assembly removal” on page 4-15.
- If the solenoid is functioning, remove the assembly and check for
blockage. Replace the assembly if necessary. See “Paper pick
assembly removal” on page 4-15.
