• Remedy: Flatbed Controller card Ensure that connectors J15, J1, and J5 are properly connected. Inspect the ribbon cable connection on CIS for proper connection. If connector J15 is properly connected, verify the following voltages on the controller card. Check pin 9 for +3.3V, pins 11, 13, and 15 for +5V. Pins 3, 6, and 8 are ground. If connector J1 is properly connected, verify the following voltages on the controller card. Check pin 19 for +12V and pin 20 for +5V. If voltages are present, replace the flatbed FRU. If there are voltage irregularities, replace the controller card.

• Code: 842, 843
• Description: 842 Scanner Failure. Communication failure 843 Scanner Failure: carriage failed to home or move to desired position
• Remedy: Flatbed Controller card Ensure that connectors J15, J1, and J5 are properly connected. Inspect the ribbon cable connection on CIS for proper connection. If connector J15 is properly connected, verify the following voltages on the controller card. Check pin 9 for +3.3V, pins 11, 13, and 15 for +5V. Pins 3, 6, and 8 are ground. If connector J1 is properly connected, verify the following voltages on the controller card. Check pin 19 for +12V and pin 20 for +5V. If voltages are present, replace the flatbed FRU. If there are voltage irregularities, replace the controller card.

• Code: 843.01...843.04
• Description: Scanner Failure ADF mechanical failure. General mechanical failure. Pick Roller engage failure. Pick roller disengage failure.
• Remedy: ADF ADF cable Controller card ADF pick pad ADF separator roller ADF paper tray and extender. ADF cover Ensure that the proper paper size is being used in the ADF. Are the paper guides on the ADF tray properly adjusted? Inspect the ADF separator roll and ADF separator pad for wear. If they are worn, replace them. If they are dirty or have a buildup on them, clean them with a damp cloth. If the ADF fails to pick check to make sure that the paper height in the ADF input tray is beneath the height marker on the ADF paper guides. Inspect the paper present sensor on the ADF. • Perform the paper present and scan first sensor tests. See “Sensor Test” • Check the flags on the sensor. Are they able to move freely? If the sensor flags are damaged, replace the ADF assembly. Make sure the ADF cable is securely connected to the ADF and the controller card. If the cable is properly connected, perform the following checks: • Check the ADF cable for continuity. • Check pin 1 on controller card connector J2 for +5V. • Pin 3 should be ground. If voltages are present, replace the ADF. If replacing the ADF does not fix the problem, replace the controller card. If the ADF is multi feeding, check the ADF pick roller and pad for dirt. Remove them from the MFP, and clean them with a lint free cloth and isopropyl alcohol. If the leading edge of the paper is damaged, instruct the user to lessen the number of documents being copied from the ADF at one time. If there are excessive misfeeds from the ADF, verify the the ADF paper tray and extender are properly installed. Skews and jams at the ADF paper present sensor might be caused by an improperly closed ADF cover. Ensure the ADF cover is closed properly.
