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.
