I recently purchased a MF634CDW direct from Canon for my home office. I set it up and seemed like all was OK, but my wife reported that the machine had an error message. I power cycled and then it seemed fine, but I now realize that whenever the device goes into sleep mode, and you send a print job, it displays an error message and you have to power cycle to get it to function again.
I am not using the wireless functionality and am using the wired network. Other then turning off the sleep mode altogether and accepting that this device has flaws, I don't have another option. I downloaded and installed the latest firmware but it did not fix the issue.

I never really found an answer. Reconfiguring the device seemed to help. When I did it, I didn't mess with as many settings and left the device driver on the PC with default port settings. Initially I tried to mess with the port settings. Sorry I could not be more help. Canon wasn't either.

I have one of these printers, brand new, just connected to a macpro with USB cable. No network connection. Printed fine for a couple times, then when I try to print, nothing happens. No alarm, alert of any kind. Just nothing. When I cycle the power, it may or may not print then. PLEASE HELP as this is ridiculous for a brand new printer.

I am having the same problem.
The printer is connected via USB cable to a MAC running on IOS 10.13.6. When I send it a print job, the printer icon shows "printing - connected to printer" and then nothing. The status bar shows all blue. There is no error reported by the driver.
I could wait several minutes and nothing would happen. To get it to print, I have to power the printer down and power it back up again and then it prints.

Hi jdgva1988.
If the USB cable is connected to a hub, please connect it directly to the computer. If it is already connected to the computer, please try using a different port or USB cable.
If the issue persists, after trying the steps above, please call call our Enterprise & Desktop Solutions Divisions at 1-866-261-9362 or 1-800-OK-CANON (652-2666), Monday - Friday 10:00 a.m. to 6:30 p.m. ET (excluding holidays).

Whether the cable is plugged in to a multiport USB or the back of the iMac, the behavior is the same. Couldn't you create a ticket for this bug in your driver software, rather that require me to call support and wait on hold to ask them to create the ticket. This is clearly a problem with your software, no troubleshooting steps could possibly be provided to resolve this, so can't you just get this in motion for all of us having this same problem?

You say you fixed this. Would you please explain how? I suspect you actually meant to say you found a workaround. By suggesting you fixed the problem, you are giving Canon an excuse to avoid fixing their software.
