4505 Paper picks during POST and/or continuously FRU ACM (auto comp mechanism or paper feed) clutch Manual feed clutch 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. Paper picks but stops half way through the printer FRU Input sensor #1 (under print cartridge assembly) and Input sensor #2 (manual) 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 3 at J20 (Tray 1 input) and pin 1 at J18 (manual input sensor). • If correct, replace the input paper feed sensor. • If these voltages are not correct, replace the controller card. 2-62 Service Manual

Paper picks during POST and/or continuously
Paper picks but stops half way through the printer
FRU
Action
ACM (auto comp mechanism or
paper feed) clutch
Manual feed clutch
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.
FRU
Action
Input sensor #1 (under print
cartridge assembly) and
Input sensor #2 (manual)
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 3
at J20 (Tray 1 input) and pin 1 at J18
(manual input sensor).
•
If correct, replace the input paper
feed sensor.
•
If these voltages are not correct,
replace the controller card.
