MF644cdw - Shows Offline from MAC

[kaushikn]

I have been struggling to get this printer to work consistently on my network from my MACs. Most of the times when I try to print, I get an error.

Opening the Settings --> Printers and Scanners --> Canon 644c,

The banner says that the printer is offline.

Under the print job I get the message Priner - Unable to find printer

• The printer is on
• The printer is close to the wifi router
• I am using a reserved ip address for the printer (so that I have the same ip each time)
• I can access the printer from the browser using the ip address
• I was able to print from a moblie phone
• I can scan from the Canon Print Business mobile app
• I have installed the latest drivers from the support site on the PCs 
• I have tried to use the Airprint driver as well as the Canon Support site drivers

None of the macs can consistently print using the print function. 

Anyone else face the same problem?

Everyone is asking the same question and then you answer each time, would be better use of time for everyone. Thanks!

I've suffered with this problem with our Canon MF642C/643C/644C for at least a year. 5 Macs, all running the latest OS. 1 MacMini (2023), 2 MacBook Pros (a 13 inch and a 16 inch, M1 and M3 respectively) and two MacBook Airs (M1 chip)

Reinstalling the printer (became a daily routine, sometimes worse than that.)

 My fix:

1. Restart the router.
2. Reset printer to factory settings (complete reset)
3. Updated printer firmware
4. Downloaded new drivers from the Canon site and installed them.

Here are some resources:

MF644cdw bonjour problem

My printer works for all our Macs as well as our iPads and iPhones.

FINALLY, Success.

Thanks! This is great information.

This is the usual answer from Canon but it’s bogus: I have Windows based systems on exactly the same network condition that work just fine. This is a Mac-specific problem.

[VideoGuy]

Yup - I think its specific to the Mac driver.  Setting the IP address as static was my -working- solution.

[Gnome1]

Well, after all this, I deleted and reinstalled the printer, and it worked. So I learned I could do that without the computer "forgetting" the printer. Thanks everyone for all the suggestions!

[VideoGuy]

..working until you lose power again. Consider making the IP address as static as suggested.

This problem appears to be Mac + Canon Unique. That's why upgrading firmware in the Canon printer and updating to the latest Canon-provided drivers for your Mac appears to solve it. Why are you saying my answer is bogus? Or were you referring to a different post???

I've had this problem several times over the last few years on my MF644Cdw; it happens every time the power goes out, or I upgrade my network. I've tried EVERYTHING listed above, wirelessly and wired and I've purchased multiple replacement printer cables thinking they were the issue. Some of the options worked after being on the phone with tech support for an hour or more.

This time, I factory reset my Mac (using OS 10.15.7) and I watched YouTube video imageCLASS Multifunction Five Line Display Wireless Setup Video for Macintosh (MF113w) which is linked on the Canon website. I noticed nothing different from the steps I'd made previously until  5:13-5:33. In the past; I didn't Add my printer because it automatically populated so I didn't have the opportunity to highlight my printer or select my printer driver from the Use dropdown. This was the simple answer to my problem. My drivers had been downloaded but weren't in use causing my printer to show as offline.

The Solution: System Preferences/Printers & Scanners

1. Highlight your printer
2. Click the - sign
3. Click Delete Printer
4. Click the + sign
5. Highlight your printer when it populates
6. Click in the Use field
7. Select your printer driver
8. Click Add

I've likely completed this step with tech support on the phone and don't recall, but it worked for me this time. I hope it helps you.

Thanks for the details!
