Problems with excessive static electricity buildup

 

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.

 

 

 

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.

Action

 

 

 

1

High Capacity Stacker

Check the autoconnects, cables and

 

Option

connectors of the option for any signs

 

 

of loose or damaged parts.

 

 

 

2

High-Capacity Output

Remove the left and right side covers

 

Stacker/Mechanical Linkage

and check all four autoconnects for

 

Assembly

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 5-19. If

 

 

the voltages are correct, reinstall the

 

 

output option and note the positions of

 

 

the torroids 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.
