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.

Output expander control

Check the output expander control board cover to make sure the

 

board cover

ESD brush ground lead is firmly attached to the output expander

 

 

frame. Also make sure the ESD brush is not loose.

 

 

 

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

 

 

 

1

Output expander option

Make sure the output expander option is the only option that is not

 

 

recognized by the base printer. If the output expander is the only

 

 

option not recognized by the printer, continue with step 2. If not,

 

 

check the autoconnects of the options not recognized and the

 

 

interconnect card and cable connections.

 

 

 

2

Output expander assembly

Check the autoconnects for damage, especially the connector pins.

 

mechanical linkage

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

 

 

bin autoconnect located on the top left rear of the printer. Go to

 

 

“Autoconnect” on page 5-6. If the voltages are correct and the

 

 

problem persists, replace the output expander option.

jammed prior to the pass thru sensor flag

202.xx Paper Jam Open Rear Door message displays; a sheet of paper feeds out to the standard bin even though bin x is selected; paper exits half way out of the redrive

Service tip: For this type of problem check the sub error codes. They can help isolate the problem. 202 Paper Jam messages can also occur prior to the output expander pass thru sensor.
