displays, paper jammed over the pass thru sensor
Action
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 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.
Action
Run the Tray x Sensor Test and check the sensor for proper
operation. If incorrect, check the following:
• Paper low sensor flag for smooth and correct operation.
• Paper low sensor for correct installation on the autocompensator
housing.
• Paper low sensor cable for signs of cuts, pinched wiring, or other
damage especially at connector J26 on the system board.
If no problem is found, replace the paper low sensor assembly. If this
does not correct the problem, replace the option system board.
