Action
If the exit sensor flag is not resting within the paper
exit sensor during POST, the MFP displays a paper
jam message. Make sure the flag is operating freely
and is correctly installed.
Make sure the input paper feed sensors are working
properly. A stuck or incorrectly installed sensor
causes this error.
Action
Check the ACM clutch for wear. The solenoid
interacts with the clutch to control the motion of the
pick tires.
If the ratchet teeth of the ACM clutch assembly are
worn or broken, the solenoid may not stop the ACM
from rotating. Replace the ACM clutch assembly if
necessary.
Check the manual feed clutch for the same damage.
Action
Make sure the input sensors are working properly.
Check for a broken or stuck flag on the input sensors.
Make sure the cables are seated on the controller card at J20 (Tray 1
input) and J18 (manual input).
Check for less than +5 V dc on pin 1 at J20 (Tray 1 input) and pin 3 at
J18 (manual input sensor).
• If correct, replace the input paper feed sensor.
• If these voltages are not correct, replace the controller card.
Action
Open the left cover, and verify the solenoid and clutch are functioning
when an attempt is made to feed the paper.
Make sure the rubber tires are installed and clean.
Replace if necessary.
Check the rear guide in the paper tray for proper adjustment.
