minolta 1080 blank copies!!!
im working on a minolta 1080 copier and the problem im having is that every single time i go to make a copy of something, the machine prints it blank... not even a spec of toner on the page. it has a brand new toner bottle, fuser but i dont know how old the drum is. the meter from inside the machine says 112,112 and the outside meter says 115 thousand. any ideas of what it could be? and they only use it as a copier.

Can you see the charge corona glowing purple? I think you may have either a failed HV (quite common) or charge is tracking to earth via the end caps of the trans/sep can or the charge corona can. Also take out the trans sep corona can and try for an image on the drum.

It's a known problem in my area since EP-1050. The EP-1080's is better but also do it during high humidity season.
We would change the TRANS/SEP Corona End Cap.

okay will check that out, i did notice though that before i cleaned the corona wires (if i remember correctly there are three) the paper would come out dirty, like excess toner or something, but once i cleaned the corona wires the page would come out really clean (but still with no image).

Note that there is no C-0200 or C-0210 (corona leakage) error code on the 1080. If an overcurrent condition exists, the hv unit simply shuts down. As others have mentioned, these hv units also have been known to fail.

All as said above +:
Replace on the HV board capacitors C101, -201, -104, -109 with the same specs. The temperature range is important.

I have at least 400 of these machine in the field still and 90% of the time the t/s coronas are bad. take the t/s unit out of the machine make a copy stop it under the drum. is there a image on the drum if yes its your t/s coronas you can clean the corona end post with a eraser and then replace the wires
if there is no image on the drum replace your HV unit.
