Just got the printer and set it up in relatively short time. Tried printing one page and scanning a page. Everything works so far, and it connected wirelessly to my network. I just had this long white plastic piece left over that I cannot figure out. I have no idea what it is for or where it goes.Maybe some day, I will figure it out. But it seems to work without it.

We've had this printer just over a year and it has been the workhorse of a small SOHO network with three computers accessing it for printing and scanning. I've had printers before that I have wanted to throw out the window and frankly was holding my breath with this one. I can finally exhale. After 13 months having gone through the starter cartridges and 30% into the new ones, I can attest to at least our experience that this is dependable and output (both scan and print) are of good quality. If I had one gripe, it may be that the software is a bit less elegant than it could be, but that was overcome with a small learning curve (for example, using the ADF to make double sided copies can be done from the touch screen - but making double-sided SCANS has to be done from the software - go figure). I give this 5 stars easily because while the learning curve is a one-and-done thing, the quality endures.

My wife and I got this printer at the start of remote work due to COVID. My job requires that I print several hundred pages per week, so we knew our old inkjet wasn't going to cut it. The MFC644 has been outstanding so far, producing excellent output at a much better speed than any inkjet. My only complaint is with the scanning function, which, as other have noted, seems rooted in 1996 tech. Wireless scanning is simply a lost cause, so I'm stuck shuttling back and forth with a thumb drive. Since the printer excels at its main function (printing) I can live with this relatively minor flaw, but wireless scanning would complete the package. Overall, two months in and we're very pleased with the printer. Hopefully it will strengthen my argument to work from home forever!

I had high hopes for this printer, however, I'm about to return it because of a paper feed error that prevents the printer from working. Out of about 10 attempts, I only was able to successfully print one document within the first week of having it. UX of touch screen leaves something to be desired too. Errors are cryptic and don't leave user with any solutions for fixing. All around bad product. Do not purchase.

It seems Canon has produced a printer of such poor quality that it should have it's own classification in the Product Hall of Shame. Nothing works easily and print quality is terrible. If you are considering this printer ... save yourself nothing but headaches and heartaches, do not buy it!

Ever since I got this printer it hasn't worked right. The quality of the document or picture isn't very well. Of course, I am no expert on printers but I have worked with a few in my 50 years and this one I would not purchase again. The system is too complicated and the screen is too hard to maneuver.

Ordered online and received printer today. So easy to setup. I connected wirelessly to my home router, was immediately able to print from Samsung laptop and iphone without downloading any software. Print quality is great! I originally wrote this review on the MF642cdw in error. I have the MF644cds model and love it!

I have a Canon MF644Cdw. Once I set up the printer drive, it prints but after a month the printer connection to my laptop stops working for no apparent reason. I keep getting error message that "cannot find printer". I have had this issue after printer drives put on two laptops. The printer works for about a month and then stops printing or connecting to my laptop. Why?

Great printer… no FAX and paper tray only holds about 100 sheets.

I bought two printers and the scanner function will not work on either. On occasion, the printers will scan but they quit after one or two scans and either the scanner can't recognize the PC or the scan utility just fails. Online help is of no use.
