i have minolta 3102 this copier is background fault on colour copy but black copy is very fine i change the all drum unit kit but no change
plz help me
Did you run the stabilizer or background reset and stabilize function? Do you have any error codes? The ATDC-sensors could sometimes clog up with toner (see http://www.copytechnet.com/forums/ko...-location.html) and give backgrounding and other issues, check the voltage and/or clean them. Good luck!
Then I'd suggest that you clean those sensors, they effect mostly colour prints and not when printing only b/w, so I suggest you take the ATDC sensors out (a service manual helps you out here), and clean them and then run the stabilization and gradiation adj. again. If you are very unsure about how to fix it, contact a technican if you aren't one yourself.
