observed during operation by removing the left, right and system
board covers. The output expander functions without the covers
installed.
Note: Make sure the option is correctly installed before attempting
to service the unit. No jumpers should be installed at connector J6
on the output expander board.

Output Expander Control
Board Cover
Printer does not recognize one or more output expander options
as being installed.
Service Tip: If more than a single output expander option is installed,
check each one to see if the printer recognizes any single option as
being installed. If the printer recognizes any of the output expander
options then the base printer autoconnect system is operating
correctly and the problem is in the unrecognized expander option.
Action
Check the output expander control
board cover to make sure the ESD
brush ground lead is firmly attached
to the output expander frame. Also
check to make sure the ESD brush is
not loose.
