The tray x option system board did
not detect a piece of paper actuating
the pass thru sensor. Remove any
jammed sheets of paper from the
printer and check the pass thru
sensor and flag for proper operation
by running the appropriate Tray
Sensor Test from the diagnostics
menu. If the test fails, check the
sensor for correct installation and
the flag for proper operation. Also
check the sensor cable to make sure
it is correctly connected to the option
system board. If incorrect, replace
the tray x option pass thru sensor
assembly.
Check these parts for signs of
broken or damaged parts,
contamination on the drive rollers or
wear plate and wear or damage to
the drive shaft bearings. Check the
drive roll assembly and skewed
backup roller for signs of wear, slick
spots, material buildup, and oil or
grease on the rollers. Also check for
proper operation of the paper
aligning assembly. Repair or replace
parts as necessary.
