Canon MF754Cdw Print quality issues

[CanonVida]

Hi everyone

We have been using a Canon MF645Cx for many years as a printer for our small business, we are still happy with it, however we need a second one because we have been growing our business

We are printing (small) labels, envelopes and general documents. The print quality of the MF645 was always very satisfactory, very sharp fonts, even with small font sizes. Print speed is a bit slow, but decent.

2 weeks ago we bought a Canon MF754Cdw and after integrating it into the network and some first tests we are extremely disappointed. Every edge, no matter if graphic or font, is very uneven / granular and not smooth at all. Especially in small fonts its extremely bad. So far I think we tried every correction / adjust mode there is and found no improvement whatsoever. Is this a problem of this particular printer or did the printing quality deteriorate so much in the newer generations?

My eyes aren't what they used to be. I don't really see any difference. The two images look identical. 🤔

I hope you were not checking them from the mobile browser, since they are heavily compressed there.
We have made some more test prints, and the printer seems to be defective. Every small font is botched, every fine line crooked. I hope the images below show it better. What part of the unit needs to be replaced?

Canon support in Europe is a disaster currently, that is why I hope to find help in the online community. Thanks

I do see some variation with the second set of photos. As Stephen noted, we are in North America, so the 754 is not a model available or supported in this country. (I'm not employed or affiliated with Canon. I'm an end user).

My suggestion would be to see if there are any Authorized Canon dealers in your area and reach out to them. Another thought might be to see if an inkjet printer yields better results than a LaserJet printer. 🤔

@CanonVida, I had a problem where the text and images looked the same way as in this zoomed image of yours - as if it has diagonal jagged on horizontal and vertical lines.
It turns out the reason is very mundane: Windows have installed a generic driver for the printer making it print at 300dpi without needed processing for laser printers. Simply manually installing the driver from the Canon site solved the issue. HTH.
