i have a strange one, intermitantly when copying we get a total Black copy , if you recyle the power the machine runs fine again till the next time!

This can be fine for a wek or two but then can also fail within the hour:confused:

What have you done to try to fix the problem? I don't want to suggest things you have already done.

Check contacts inside drum unit opening. Check connectors on high voltage board

I was thinking more along the lines of exposure lamp failing to light or primary charge loss. Can you reproduce the problem? =^..^=

Does it happen only when doing a copy or also when printing. I usually go into Function and run the F12 test pages to eliminate the scanner.

Something like that.
