    Communication default between MCU and HVPS , 5 V is missing.
    Cyan drum cartridge fault. Replace cyan drum.

    or try this:

    There is +5 VDC from P/J574-5 to P/J574-4 on the HVPS Control PWB ?

    Disconnect P/J574
    There is +5 VDC from J574-5 to J574-4.
    There is +5 VDC from P/J406-B5 on the MCU PWB to GND

    Check for open circuit or loose connections in the 5VDC supply wires between P/J406, pins B5 and B6; and P/J574, pins 5 and 4.

    Check the wire from J406-B5 to J574-5 for a short circuit to GND. If the wire is OK, replace the HVPS Control PWB

    Switch off the power. Check these wires for an open or short circuit to GND:

    • <LI id=svc.imper.0000647840>HVPS Control PWB P/J574-9 to MCU PWB P/J406-B1.
      <LI id=svc.imper.0000647844>HVPS Control PWB P/J574-8 to MCU PWB P/J406-B2.
      <LI id=svc.imper.0000647848>HVPS Control PWB P/J574-7 to MCU PWB P/J406-B3
    • HVPS Control PWB P/J574-6 to MCU PWB P/J406-B4.
    If the problem continues, replace the MCU PWB ( PL 13.1). If this does not resolve the problem, replace the HVPS Control PWB ( PL 9.1).
