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 have noticed that since I did my workaround by accessing the printer through the browser interface that my printer is no longer having a problem waking from sleep. The last few mornings I have started to print without first employing the workaround and the printer woke and ran the jobs. I am totally baffled.

When I send a job when the printer is asleep, I have to do these things... 1.) send the job 2). reach over and wake up the printer, 3.) (standup) & disconnect the usb connection cord, wait 30 seconds 4.) plug it back in & wait. It takes a few seconds, but it always works. It is just a huge frustration.
If I send the jobs, while the printer is turned off....when I turn on the printer, the jobs run fine. It is only when the printer goes to sleep.

What is a "workaround " - I am a tech dunce.

A workaround or kludge is a way to get something broken to work without actually fixing it. In this case, accessing the web interface to the printer in a browser to wake up the printer without having to reboot it.

No, that doesn't work with this printer.

As part of my workaround I went into my router and set up the printer on a static IP. Since doing that I no longer seem to need my workaround. Could it be that the router has reassigned the DHCP IP address of the printer but my PC's don't know about it? This won't help people using a USB cable, but wireless and ethernet users might want to try it.

I have always had a static IP on mine. Still had problems. I was using Airplay and tried LPD as I'm on a Mac and still had issues.
I am now using IPP (Internet Printing Protocol) and did the fix I mentioned earlier by using the hidden buttons, if it is still posted, and so far I haven't had any problems. I had one hicup and hoping that was it. But I have my doubts.
