Output Expander Service Check
There are two levels of the 500 Sheet Output Expander Option.
•
Level 1 is equipped with a stepper motor/mechanical linkage
assembly.
•
Level 2 is equipped with a DC servo motor and a new
mechanical linkage assembly and has fewer mechanical
components.
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.
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.
