4061-xx0 The printer does not recognize one or more output options as installed Service tip: If more than a single output option is installed, check each one to see if the printer recognizes any single option as installed. If the printer recognizes any of the output options, the base printer autoconnect system is operating correctly. The problem is in the unrecognized option. Continue with this service check or go to the service check for the failing output option. FRU 1 High-capacity stacker feeder 2 High-capacity output stacker/mechanical linkage assembly Action Check the autoconnects, cables, and connectors of the option for any signs of loose or damaged parts. Remove the left and right side covers and check all four autoconnects for damage, especially the connector pins. Remove the output option and check the voltages on the standard output bin autoconnect located on the top left rear of the printer. Go to "Autoconnect" on page 5-6. If the voltages are correct, reinstall the output option and note the positions of the toroids on the autoconnect cables on the upper and lower assemblies, and check the voltages on the autoconnects. If all voltages are correct and the lower assembly is failing, replace the lower control board. Otherwise, replace the High-capacity output stacker option. 202.xx Paper Jam Open Rear Door displays and a sheet of paper is jammed prior to the pass thru sensor flag or 202.xx Paper Jam Open Rear Door displays, a sheet of paper feeds out to the standard bin even though bin x is selected and paper exits half way out of the redrive assembly Service tip: For this type of problem check the "Base printer sub error codes" on page 2-9. They can help isolate the problem. A 202 paper jam message can also occur prior to the high-capacity output stacker pass thru sensors. FRU 1 Lower Pass Thru Sensor/ Flag Assembly Action Check the flag for correct operation, binding, broken parts, or interference from the sensor cable. If incorrect, repair as necessary. If correct, check to make sure the lower pass thru sensor is correctly connected to J3 on the lower control board. Disconnect the pass thru sensor cable and check the voltage at J3-3. The voltage measures approximately +5 V dc. If incorrect, check the voltage at J3-2. The voltage measures approximately 0 V dc. If incorrect, replace the sensor assembly. If this does not fix the problem, replace the highcapacity output stacker option. Remove Paper - Output Bin x Full displays; you may not be able to clear the message FRU 1 Dual output bin sensor flag (upper assembly) Action Check the flag for correct operation, binding, broken parts, or interference from the sensor cable. If incorrect, repair as necessary. Diagnostic information 2-101
