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).
