Canon Imageclass MF656Cdw scanner quality & artifacts


Recently got an Imageclass MF656Cdw to replace an old Epson Worforce WF-3520, and found the quality of the scanner to be extremely poor compared to the Epson, both at 600dpi with same settings. The scans from the Canon are more blurry and with fewer details than the old Epson, but more concerning is that it creates a lot of rectangular artifacts in dark areas of photos. Please see images attached for examples.

Does anyone experience similar issues with their scanner? Not sure if there's any setting change I could try, as all attempts to increase quality have been in vain.

That, and any other details you'd like to give will help the Community better understand your issue!
