Could someone please help me here?
I'm trying to find out what's causing a Konica 7075 to output light copies randomly (by "randomly", I mean that, when taking 5 copies, the order could be: good, good, light, good, light; and a light copy can mean "completely light" or just "partially light").
If this wasn't odd enough, the machine only does it when working with A4 paper - if you put the paper on the A4R position, the problem goes away.
I've ruled out everything I could think of: drum ground, charge and transfer corona's and their respective HV boards and door switches.
Any suggestions? Thanks!
