High-capacity output stacker service check

Service tip: The majority of the mechanical components can be observed during operation by
removing the left, right, and front 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.
See "High-Capacity Output Stacker Board" on page 5-14
at J6 for the upper and lower units.
Problems with excessive static electricity buildup.
FRU
1 Front Cover Assembly
The printer does not recognize one or more output options as installed.
Service tip: If more than a single output option is installed, check each one to see if the printer
recognizes any single option as installed. If the printer recognizes any of the output options, the base
printer autoconnect system is operating correctly. The problem is in the unrecognized option.
Continue with this service check or go to the service check for the failing output option.

Service Manual
Action
Check the front cover assembly to make sure the ESD brush ground
lead is firmly attached to the high-capacity option. Also check to
make sure the ESD brush is not loose or damaged.
Action
Check the autoconnects, cables, and connectors of the option for any
signs of loose or damaged parts.
Remove the left and right side covers and check all four
autoconnects for damage, especially the connector pins. Remove the
output option and check the voltages on the standard output bin
autoconnect located on the top left rear of the printer. Go to
"Autoconnect" on page 5-1. If the voltages are correct, reinstall the
output option and note the positions of the toroids on the autoconnect
cables on the upper and lower assemblies, and check the voltages on
the autoconnects. If all voltages are correct and the lower assembly
is failing, replace the lower control board. If the upper assembly is
failing, replace the upper control board. If the voltages are incorrect,
replace the upper or lower failing mechanical linkage assembly.
