250/550-sheet transport motor failure service check
Action Yes No
Step 1
Remove all input options and re-install only the suspected 250/550-sheet
tray option. POR into diagnostics mode and navigate to:
INPUT TRAY TESTS > Feed tests > Tray 2
Does the input option feed normally?
The problem may not
be on this option tray.
Re-install the
remaining input
options one at a time
and test each option
for errors. Proceed
with the appropriate
service check based on
the error message and
the input option being
tested.
Go to step 2.
Step 2
Remove the tray from the drawer and do the following:
• Check the paper guides for damage. Move the paper guide and verify
if it can move freely from one position to another.
• Check the media size finger flag for damage.
• Check the lift plate gear for damage. Manually turn the lift plate gear
and check if it causes the lift plate to move upward.
• Check the separator gears for damage. Manually turn the gear and
check if the gears function properly.
Are the above components ok?
Go to step 3. Replace the media tray.
Go to “Media tray
assembly removal” on
page 521.
Step 3
Open the left cover and do the following:
• Reseat the connector (J10) on the controller board.
• Check the motor cables. If damaged, then replace the transport motor.
See “Drawer transport motor removal” on page 530.
• Remove the media tray. Manually turn the transport motor encoders,
and check if it causes the transport and separator gears to turn. If there
is a problem with the gears, then replace the input option. See
“250/550-sheet media tray option removal” on page 521.
Replace the transport motor. See “Drawer transport motor removal” on
page 530.
Does the error remain?
Replace the input
option. Go to
“250/550-sheet media
tray option removal”
on page 521.
If the error persists,
then go to step 4.
The problem is solved.
Step 4
Remove the 250/550-sheet input option and check the upper interface
cable. If damaged, then replace the upper interface cable.
