MF 743 CDW Imageclass wont correct color mismatch

[Rhyschip]

I have a Canon MF 743Cdw Imageclass Color Laser all in one printer. I just replaced all the toner cartridges and it appears to be color mismatched. I did the correct color mismatch function on printer. But it it goes throught he motions and states it cant correct this function. , or something like that.

Are the replacement toner cartridges Canon branded, or are they something else? If they are OEM toner cartridges, and the cartridges are properly installed, try defaulting the printer's programming and start from scratch. If that doesn't work, reach out to Canon Customer Service to determine if the unit needs to be serviced.
