More than likely you have a bad toner cartridge.

SOURCE: Printing black smudges across the page at 10 cm intervals

Most likely cause by the drum unit. Replace drum or upgrade printer.

SOURCE: too much toner on paper which then smudges

Try reducing the print resolution using the menu buttons. Does it smudge with coloured prints? If so then the fuser unit is faulty. If it is only black that smudges it is likely to be the K Developer unit. Ensure that you are using genuine toners, not refills or third party as the quality of toner can cause similar results.

My bizhub c451 is still printing only cyan and black after we change toner catridge, what could be the problem please


The problem could be the laser that scans the image or the detectors that see the colors. It could also be a problem with the power supply or the main board. This is not going to be cheap. If you want to continue, you should download the service manual.

How do i reset the trouble code c 2259


Black image unit motor failure. First open the front door remove the black image unit not the black toner!!!. Take the image unit and shake it so as to spread out all of the developer & toner inside the image unit along the whole length of the unit. The reason for this is as not have all of the developer/toner all at one end and the motor trying to turn with all that at one end or the other. Never store image units or toner vertically!!!!!
Now reinstall the image unit. and close the door. Opening and closing the front door will reset the machine . If it comes back good chance bad image unit.

Replaced the K imaging unit. The new unit does not reflect it being replaced on the copier. Consumables screen shows the K unit at empty still.


"K" is refereeing to the black toner not being full.... I would replace the Black toner bottle. The toners do have a chip on them, you may have got a defective one..... Good Luck

Bizhub c451 error code c2259?


Black developer motor failure to turn. You mite try pulling out the Black image unit and shake it to spread the toner and developer along the whole unit. The image unit mite have been stored standing up image units should always be laid flat. All the developer may be sitting at one end of the image unit an so the motor is having a difficult time turning.
