Action
Check tray for paper catch points.
If the sheet being fed stops
momentarily, the ACM applies
additional vertical force causing
additional sheets to feed.
Do not mix paper types.
Check the tires in the ACM assembly
for signs of wear or damage.
Replace the tires as necessary.
Open left cover and observe the
solenoid and clutch actions at the
ACM and manual feed shafts as a
print job is attempted.
Replace the faulty part.
Disconnect the solenoid cable at J5
on the controller card.
Measure the resistance across cable
pins 1 and 2 and then pins 3 and 4.
• The resistance should be
180–210 ohms.
• If it is not, call the next level of
service.
• If the resistance is 180–210 ohms,
check the controller card. See
