Question about Canon imageCLASS MF6530 All-In-One Printer
The Presence and absence of the charge on фоторецепторе in analog device is conditioned that that light reflected from original, gets on photo drum and discharges (it), accordingly from light, white, not containing scenes area, is reflected more light, than from black, containing scene area. Accordingly drum runs down where is absent the scene. The Toner has opposite drum sign of the charge, accordingly toner is carried on that area drum, on which is present the charge (the opposite charges are attracted).
More simply, in analog device toner lies on charged area drum.
In цифровом device all on the contrary. The Drum is exhibited (get lighting) by ray of the lazer i.e. there, where shines the lazer, drum runs down. The Toner in digital device has such sign of the charge, as drum so he lies on discharged area drum.
Now we shall consider the main reasons of the origin of such sort to faults, as white sheet (the absence of the scene on copies) and black sheet (potting the sheet on the whole surfaces by toner).
1. Absence of the voltage on коротроне (roller) of the carrying (also is identified lower)
2. Does Not revolve фоторецептор (фотобарабан)
3. Absence of the earth фоторецептора (фотобарабана)
4. Problems with high-tension power supply unit (HVPS) (brings about that that is specified in p.1)
5. Is absent voltage of the offset of the magnetic gross, check contact on magnetic gross (particularly often on HP LJ1010 - break spring-contact when leading-in)
6. Distance from magnetic gross before drum more prescribed - a toner is not carried
7. Is Not exhibited drum lazer does not shine, locked шторка lazer, physical obstacle for ray, problems with lazer or management him
