SOURCE: Minolta 2300DL ghosting

Hi,

I just had the same problem with my 5430DL. It was a bad toner cartridge. The bad cartridge is at 73% full, and had not been a problem until recently. I had been troubleshooting and finally remembered that I had the old cartridge with toner still left. I swapped them out and no more ghosts. Swapped back and the ghosts came back. I have ordered another new toner cartridge and fully expect the problem to be resolved.

SOURCE: Magicolor 2300dl ghosting and smear - black only

if only black does that, then it can be black toner, but the best way to find out, print something and when printer starts to take paper open front door, remove waste toner box and take out pc drum and transfer belt and check the printed page from there, if it seems ok, print nex page and open door when page comes out from fusin unit, if quality goes bad before fusing unit, it may lead to 2'nd transfer roller / pc drum and transfer belt quality was ok / if after FU then you have a problem in fusing unit.

I have a KM bizhub c 451 black imaging unit that prints faintly. I have replaced the following parts, PC drum, PC charger and starter( developer), yet it is not printing solid black.


replace the black image unit as a whole you do not replace the units as individual parts. Where did you get the drum from? or the PC charger as they come as one and you don't replace the developer as it is located inside the unit!!!!!!

Poor print quality


The "ghost" image is "burned" onto the drum.

A laser printer is supposed to charge specific "dots" on the drum, and the toner-ink is supposed to stick only to those "dots", the paper is pressed against the drum, and then the "fuser" uses heat to "melt" the toner-ink onto the paper, to produce the printed page.

You need to replace the drum.
