Action
Open the left cover, and verify that the solenoids and clutches are functioning
when an attempt is made to feed the media.
Make sure the rubber tires on the ACM are installed and clean.
Replace the tires, ACM drive, clutch assemblies, solenoids, or drive shaft as
necessary.
Action
Check tray for media catch points.
If the sheet being fed stops momentarily, then the ACM applies additional vertical force,
causing additional sheets to feed.
Do not mix media types in one tray.
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 J26 on the controller board and measure the resistance
across cable pins 1 and 2.
• The resistance should be approximately 70 ohms.
• If it is not, then replace the solenoid.
• If the resistance is approximately 70 ohms, then check the controller board. Pin 1 at
J26 should be +24 V dc. See
more information.
Replace controller board as necessary.
Action
Check tires for debris. If tires are new, then try reversing each on its hub.
Check side guides on Tray 1 and Tray 2. Guides set for a full stack of media may
be too wide when the stack is short.
