Diagnostic Information

4069-5XX/7XX
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
Option 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 - Top” on page 5-11 .
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.
