Did you fit a NEW black image unit or a used one? if not new replace it with a genuine KM drum & toner.

Wow, looks like the old Toshiba "reverse image" mode..You could print this out in case some one used the last copy and reverse image it again..I say this thinking that it could be some kind of power supply problem... charge and transfer leads switched....is this toner on the page, developer, or both???As a side note..THE C3350 SUCKS!!!

The sample with the image inverted looks like its not getting any charge. Changing out used units is not recommended. Probably ok to change out temporarily.
If you find a good used unit you need to reset it. It runs TCR adjustment and on these it set the key color position. So you can get developer and color registration problems.

Only one way to know is to replace the black image unit.


So you refill the toners? Where do you get your toner and chips from?
