Hi I have an bizhub c 250 now it start to print just magenta , all other cartridges are full please if you hwve procedure to reset the imaging unit to default factory settings . thanks

replace the black and magenta image units

Magenta Print head (print head has the LASER inside of it that writes the image on the drum) in this case it is the magenta LASER. Open and close the front door to reset. If it comes back replace the print head. Normal done as a set of all four. (Black, Magenta, Yellow, and Cyan). Worse case is the relay board is bad or the Image control Board$$$$$$$$$$$$$$$$.

Hi,
I suggest you contact Konica Minolta bizhub printer support technician, Because may be dust available in printer so not access full cartridge. So first full servicing and then you used or change cartridge in printer.

Thanks,

replace the magenta image unit

If the message Change Imaging Unit Magenta displayed refer to imaging unit with contents a developer.The Imaging unit life is 80.000 copies.
The imaging units located after front door when is located the waste toner box.
If the message M toner end/change the M toner displayed refer to toner cartridge
The toner cartridge life 15.000 copies 5% saturation.In full color mode the color saturation is 80% and the color toner life is 6.000-8.000 copies.
I think your problems is a toner not the developer.

Change the chip or enter in service mode and change the imaging unit life duration to long life.The copier displayed continuosly Please change the image unit,press OK and ignore.

Hi armaskopljak:
You have replaced the toner cartridge but you still have to replace the imaging unit which is the drom that the toner cartridge attaches to.
Toner Cartridge OK, Low, Empty When 15,000
(high-capacity cartridge) or
7,500 (standard-capacity
cartridge) pages are
printed (5% print density).
Imaging Units At/Near end-of-life When 30,000 pages are
printed out or when the

A fuse in the new

upon installation,
resetting the counter.
Verify color calibration. Clean lenses.

Turn the unit off. Remove the cartridge and shake it back and forth. Ten place it and turn the unit back on. Also you can reset the counter on the cartridge, go to UNI KIT and look under Brother TN 110 refill support. These people sell refills. The ink you get with he printer is minimal. Also turning the printer off and back on will help with resetting. I found that there is plenty of toner left when the warning comes on.

sounds like the wrong image unit. Oce and ollivetti have the same machine and take the same image unit but with a different chip. Make sure it is a genuine konica minolta image unit. If need be try putting the chip from the old unit on the new one and see if lays down the colour
