Re: MF634CDW Not Waking from Sleep when print job is sent

Canon, apparently this issue has not been resolved. Everyone has been told different workarounds, but no definite answer. I just paid a good chunk of change for what I thought would be better than my Brother printer, but if it won't print without all this drama, it is definitly far worse. We were told this was one of Cannon's newest printers and assumed it would be great. Please help this to be true by fixing this bug! I hope to hear back soon!

Re: MF634CDW Not Waking from Sleep when print job is sent

I just setup this machine in one of our shops, imedialty saw similiar issue. The printer will go into sleep mode and disconnect from the wireless network. Sending a print job does not trigger the printer to wake up, and why would it?

 

Looking at the settings for the wireless setup, there is a an eco mode. I turned this off, and the printers wireless connection stays connected even if it has gone into sleep. 

 

Problem solved for me.

Thank you for the post! I am going to do it. Appreciated!!!

When I’m not home and the kids need to print something I get a call at work. So annoying. Thanks again!

OK, I think I have successfully solved this issue on my network - the resolution is specific to ASUS router.  I would guess similar settings exist on other routers.

 

Check out this post ( I am copying over so the instructions are not lost) - FOR ASUS ROUTERS ONLY

 

  1. First log into the router’s settings.
  2. Choose Wireless > Professional tab
  3. Make the following changes:
    • Modulation Scheme: Up to MCS 9 (802.11ac)
    • Airtime Fairness: Disable (NOTE: According to one reader, this is the only change that matters, so try this first. Thanks Dan CC!)
    • Multi-User MIMO: Disable (Note that this was already disabled by default for me)
    • Explicit Beamforming: Disable
    • Universal Beamforming (5 GHz only): Disable
  4. Click Apply button.
  5. Each of the Bands (i.e., 2.4GHz and 5GHz) have their own independent set of settings on this page. So, change the Band and repeat Step 3.

 

This solved pretty much all issues for me. I can print when the printer is sleeping, it wakes up, prints, and goes back to sleep again.

Also similar to this thread.

 

Edit : 8/7/2019 - I have returned the printer since it doesnt work with Unifi / Amplifi which is the gold standard for high throughput pro/ semi pro wifi systems. Too much headache.

I would very much like to follow these instructions, but none of the things you list under the "professional" tab are listed for my rouer. I have the ASUS RT-AC55U. Please help - thanks!

Thank you for sharing what worked for you and congratulations on successfully troubleshooting your issue.

 

For the benefit of others, I just want to point out that I can see from your instructions that the problem you are solving is for a wireless connection. That type of connection is always trickier than a hard-wired connection.

 

Many of us are still waiting for canon to solve their problem with hard-wired connections, for which their printer driver's failure has no excuse.

Hi katmichaels.

 

It is recommended that you contact your router manufacturer for assistance with your router settings.

Re: MF634CDW Not Waking from Sleep when print job is sent

Thanks. yes, I solved the Wifi problem but honestly only the Canon printers have this issue. I have a Kodak and HP printers and both of them work without modifying anything on my router. This is 2019, and Canon needs to act like it is 2019.

This is not more than a week's worth of effort for Canon and I am surprised they are still directing people to contact the router guys.

Just for me personally, this will be the last Canon printer I will buy. I was able to return the printer to Best Buy even though i solved the issue. I cant take the headache of fixing stuff that should not be broken in the first place. Because believe it or not, this printer doesn't work with Unifi routers. I mean JFC! There are not that many things that dont work with unifi, but I found an exception.


I am not bitter - I am practical. The solution works in limited cases and the manufacturer (Canon) just needs to step up. Look at @patrice above - asking people to contact the router manufacturer. Ha ha.

Re: MF634CDW Not Waking from Sleep when print job is sent

I have had my MF634Cdw for over a year; every time Canon updates the drivers, I have issues with getting anything to print.  This last update 7/26/19 changed my printer type to "AIR PRINT" . I have no idea what that is.  

 

But this not waking up from sleep mode could be my problem, thought it has not ever happened before.  How would I turn that Sleep mode off?
