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?
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?
Step 3
Remove the tray from the drawer and do the following:
•
Check the pick roller's position. The pick roller should not hang
vertically; it should lean horizontally underneath the top cover of the
drawer.
•
Make sure the pick roller is installed correctly. If not, then re-install
the pick roller.
•
Lower down the pick roller and then release. Check if the pick roller
would spring back to its original position.
•
Check the pick roller for damage. Check for wear on the pick tires.
Are the above components ok?

The problem may not
be on this option tray.
Re-install the
remaining input
options one at a time
