High voltage power board: Charge voltage output error [M]
The measured voltage is
not proper when EGB

1. Check the connectors.
2. Replace the PCU for magenta.
3. Replace the drum positioning plate.

Anyone else ever had a reoccuring SC 301 on this model ?
My problem child seems to do it after wake up each morning - I have latest firmware installed, and have tried another entire faceplate ( containing all the HVT contact pins....)
