4060-xxx Envelope feeder service check Service tip: Check the envelope feeder paper path for any debris, pieces of envelope and so on. If any other options are installed make sure they are operating normally. If only the envelope feeder is failing to operate correctly, continue with this service check, otherwise verify the interconnect card is functioning properly. Service tip: The envelope feeder receives its +5 V dc operating voltage from the +24 V dc bulk at J17. If +24 V dc is not present at J1-7, tray 1 is the only tray that is recognized. Note: If a 260 Paper Jam Check Envelope message displays, check the "Sub error codes for 9xx and 2xx error codes" on page 2-5. Printer does not recognize the envelope feeder as an attached input option. FRU 1 Envelope feeder 2 Front autoconnect on printer 3 Autoconnect on the envelope feeder Action Make sure the envelope feeder is correctly installed and mated to the autoconnect at the front of the printer. Check the connector for signs of damage to the connector or contacts. If you find damage, replace the damaged cable/connector assembly. Remove the envelope feeder and check the voltages at the autoconnect on the front of the printer. If incorrect, check the interconnect board. If correct, reinstall the envelope feeder and continue with step 3. Check for damage to the connector or contacts. If you find damage, replace the damaged cable/connector assembly. Disconnect the autoconnect cable at J1 on the envelope system board and measure the following voltages: • J1-3 measures +5 V dc • J1-5 measures +5 V dc • J1-7 measures +24 V dc If any of the voltages are incorrect, replace the autoconnect cable/ connector. If the voltages are correct, replace the envelope system board. Operator panel displays 260 Paper Jam immediately when envelope feed is requested-POST incomplete. FRU 1 Pass thru sensor Action Check for any debris or pieces of envelope over the pass thru sensor. Check for correct installation of the pass thru sensor flag. Make sure the sensor cable is attached to the envelope system board. Perform an envelope feeder sensor test to check both the sensor and sensor flag. Note: It may be necessary to use a small tool to actuate the sensor flag because it is located under the front cover. Be careful not to damage the flag. If the test fails, check the flag for damage or binds. If incorrect, replace the flag. If the flag is operating correctly, check the voltage at J3-3. The voltage measures approximately +5 V dc. If incorrect, replace the envelope system board. If correct, check the voltage at J3-2. The voltage changes from 0 to +5 V dc when the flag is moved in and out of the sensor. If incorrect, replace the sensor assembly. If this does not fix the problem, replace the envelope system board. Diagnostic information 2-49
