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?

This is not a MAC issue, its a network issue.  Using DHCP is fine for visiting devices.  Devices which come and go from your network.  For persistent devices (like printers and network attached storage) assigning a static IP ensures the destination of the device will not change.  It is an effective and reliable way to ensure a device on your LAN is always reachable.  Its easiest to assign or reserve an IP for a device on your router.  It only needs to be done once and ensures the device can always be found at its assigned IP.

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???

Problems emerged again for me.  So I did the following:

1. Deleted the MF644 printer inside System Settings on one of our Macs.

2. I locked the MF644 to a static IP address (done in the router.) 

3. Updated the printer driver for the MF644. Then tested. Printing works fine! But I couldn't get the scanner working in this configuration. Drat.

4. I reviewed apple docs and support community and learned how to do a Printer services reset inside the Mac. Here's the instructions for that:

RESET MacOS PRINTER in Settings as follows
How do you reset a Canon printer on a Mac?

On your Mac, choose Apple menu > System Settings, then click Printers & Scanners in the sidebar. (You may need to scroll down.) Control-click the printer in the Printers list on the right, then choose Reset Printing System.

You're done. Well, I was done! 

Reinstalled, with no problems with Bonjour, with full printer and scanner functionality and I am again a happy guy!

Well, I think you're quite right but this is better described as a Mac+Canon problem or a Canon+Mac problem.
