Output Expander Service Check
Service Tip: The majority of the mechanical components can be 
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.
Problems with excessive static electricity buildup.
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.
