Pass thru sensor and flag assembly:
The tray 2 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 2 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 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.
