covers. The high capacity output stacker option functions without the
covers installed.
Determine which paper path stacker assembly is not functioning
properly.
Make sure the option(s) are installed correctly and the machine is
configured correctly before attempting to service the high-capacity
output stacker option.

Action
Check for correct installation of
the sensor cable at J5 on the
control board. If either the Bin Full
(F) or Bin Near Full (NF) fail the
sensor test then check the voltage
at J5-3 and J5-4. The voltage
measures approximately +5 V dc.
If the voltage is incorrect, replace
the control board. If correct,
replace the sensor assembly.
