The printer detects paper out in tray

when adequate paper is installed in the tray.

Tray

does not detect size media installed

Step

Actions and questions

Yes

Run Tray

Sensor Test from the Diagnostics Menu.

Does the test pass for Sensor L1?

Go to step 5

Go to step 2

Check the cable connection for the paper level sensing
assembly to tray

system board.

Is the cable correctly installed?

Go to step 3

Install the cable
correctly.

Check the paper level sensing assembly for correct
installation.

Is the paper level sensing assembly installed correctly?

Go to step 4

Reinstall the
assembly if not
installed
correctly.

Check continuity of the paper level sensing assembly
cable.

Do you measure continuity?

Go to step 5

Replace the
cable.

Check the paper level sensing assembly for correct
installation. Check the following for damaged or broken
parts:

• Paper level sensing flag bellcrank
• Paper level sensing flag
• Paper level sensing flag spring

Is the paper level sensing assembly installed correctly?

Replace the
paper level
sensing
assembly.

Go to step 6

Make sure the paper level sensing assembly arm goes
all the way through the bottom of tray

Does the arm extend all the way down through the
bottom of the tray?

Recheck the arm.
If the problem
continues,
replace the paper
leveling sensing
assembly. If the
problem still
persists, replace
the tray

system

board.

See why the arm
is not extending
all the way to the
bottom of the
tray. Repair as
necessary.

Step

Actions and questions

Yes

Is the tray set for the size paper loaded in the tray, and
are the restraints in the correct location?

Go to step 2

Set the correct
size

Are there damaged or broken size sensing gears or
size sensing barrel cam in the tray assembly?

Repair or replace
defective parts.

Go to step 3

Check the media size sensing assembly for any signs
of damaged, binding, or broken parts.

Are there broken or damaged parts?

Replace the
media size
sensing
assembly.

Replace the
electronics/size
sensing
assembly.
