and theres 2 hv boards. the upper one does 1st + 2nd transfer and belt cleaning, the lower provides all HV to the imaging units..

repeditive developer spilling issues that arent caused by other malfunctions are usually a result of the lower board, which is also the biggest pain in the backside to change of the two.
