2-110 Service Manual
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.
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.

Check the autoconnects for damage, especially the connector pins.
Remove the left and right side covers. Remove the front control board
cover. Check the cables at J1A, J1B, J2A and J2B on the control
board to make sure they are attached securely and correctly.
Remove the output expander and check the voltages on the output
