• Code: 842.xx
• Description: Service Scanner This error indicates that a scanner communications failure.
• Remedy: 1 Scanner control card to flatbed inteconnect card cable Check for correct installation of the scan control to flatbed interconnect card cable. 2 Motor drive card to flatbed interconnect card cable Check for correct installation of the motor driver card to flatbed interconnect card cable. 3 Motor driver card Flatbed interconnect card If the cables are good and are properly connected, replace the following FRUs in the order shown: • Flatbed interconnect card assembly • Motor driver card assembly

• Code: 843.00
• Description: Service Scanner This error indicates that a problems has been detected with the flatbed carriage mechanical hardware.
• Remedy: 1 Flatbed scanner CCD drive shafts Check to make sure that both of the CCD drive shafts are correctly installed. If correct, go to step 2. 2 Flatbed CCD module assembly ribbon cable Check to make sure that the flatbed CCD module assembly is connected correctly to both the CCD module and J2 on the scanner control card. If correct, go to step 3. 3 Flatbed CCD module assembly Check the flatbed CCD assembly for any signs of damage and for proper mechanical operation. If any problems are found, replace the flatbed CCD assembly. If the flatbed CCD assembly is replaced, it is necessary to perform scanner registration. See “Scanner registration”. 4 Flatbed CCD scan motor/ cable Flatbed interface card Check for correct installation of the CCD scan motor cable to both the motor and to the flatbed interface card at CN2. Enter the Diagnostics Menu (turn on MFP while holding 3 and 6), select SCANNER TESTS, and select Feed Tests.If the motor does not turn during the scanner Feed Test, check for any signs of binds or mechanical problems. Repair as necessary. If no problem is found, go to step 5. 5 Flatbed home sensor cable Flatbed home sensor Flatbed interface card Check to make sure that the home sensor cable is correctly installed to both the home sensor and to CN4 on the flatbed interface card. Check for correct operation of the home sensor. If it does not operate correctly, replace the FRUs in the following order: • Flatbed interface card. See “Flatbed interconnect card removal”. • Flatbed home sensor. See “Home sensor removal”. If the problem persists, go to step 6. 6 Flatbed scanner assembly If the 843.00 error code continues to be displayed, replace the complete flatbed scanner assembly. See “Flatbed scan assembly removal”. Note: If the flatbed scanner assembly is replaced, it is necessary to perform scanner registration. See “Scanner registration” on

• Code: 845.00
• Description: Service Image Processing Unit This error code indicates a failure of the image processing ASIC.
• Remedy: Replace the scanner control card (SCC). See “Scanner control card removal”.
