Diagnostic information 2-111Output expander service checkService 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 installedat connector J6 on the output expander board.Problems with excessive static electricity buildupPrinter does not recognize one or more output expander options as being installedService tip: If more than a single output expander option is installed, check each one to see if the printerrecognizes any single option as being installed. If the printer recognizes any of the output expander options thenthe base printer autoconnect system is operating correctly and the problem is in the unrecognized expanderoption.202.xx Paper Jam Open Rear Door message displays; a sheet of paper is jammed prior to thepass thru sensor flag202.xx Paper Jam Open Rear Door message displays; a sheet of paper feeds out to thestandard bin even though bin x is selected; paper exits half way out of the redriveService tip: For this type of problem check the sub error codes. They can help isolate the problem. 202 PaperJam messages can also occur prior to the output expander pass thru sensor.FRU Action1 Output expander controlboard cover Check the output expander control board cover to make sure theESD brush ground lead is firmly attached to the output expanderframe. Also make sure the ESD brush is not loose.FRU Action1 Output expander option Make sure the output expander option is the only option that is notrecognized by the base printer. If the output expander is the onlyoption not recognized by the printer, continue with step 2. If not,check the autoconnects of the options not recognized and theinterconnect card and cable connections.2 Output expander assemblymechanical linkageCheck the autoconnects for damage, especially the connector pins.Remove the left and right side covers. Remove the front controlboard cover. Check the cables at J1A, J1B, J2A and J2B on thecontrol board to make sure they are attached securely and correctly.Remove the output expander and check the voltages on the outputbin autoconnect located on the top left rear of the printer. Go to“Autoconnect” on page 5-7. If the voltages are correct and theproblem persists, replace the output expander option.FRU Action1 Output expander drive beltPulley drive beltIdler pulley belt tensionspringCheck to ensure the output expander drive belt is correctly installedon the drive pulley and belt idler pulley. Check the belt tension springto make sure it is not loose or broken. Repair as necessary.2 Mechanical linkageDC motor assembly If the DC motor is functioning properly check the gears, clutch, andother linkage parts for correct operation and wear, broken gear teeth,or damaged parts. If incorrect, replace the output expander option.
