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 to identify the correct jumper locations
at J6 for the upper and lower units.
Problems with excessive static electricity buildup.
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.
FRU Action
1 Front Cover Assembly 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.
FRU Action
1 High-capacity stacker
feeder Check the autoconnects, cables, and connectors of the option for any
signs of loose or damaged parts.
2 High-capacity output
stacker/mechanical linkage
assembly 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.
