I have had a Pixma 922 multifunction printer for around a year. It's connected to my Ethernet network and has a static IP address on my LAN. All of my computers are Macs. I am on firmware version 3.031. Also, as others have suggested elsewhere, I have IPv6 disabled on the device.
The printer works great immediately after it's powered on. I'm able to use the scanner, printing functions, and so forth from any computer on my network. However, after the printer is idle for around 2 minutes, none of the computers on the network are able to find the printer using any printing or scanning functions. The really strange aspect of this is that the printer can still be pinged, and I can get to its embedded web browser at any time. None of this wakes the printer up, though--I have to power it off and back on every time I want to use it, and I have to start using it very quickly after resetting it.
I've removed/updated/reinstalled the drivers many times with no effect. Switching it to wireless or USB does not help.
Do you have any suggestions or advice for me, please? I like the printer, but as you can imagine, this is VERY frustrating and I have looked everywhere on the web for a solution. Any help would be appreciated.

With the information provided, I would recommend power cycling the network, resetting the network card on the printer. Disabling the IPv6 and the Wired LAN DRX setting. The following steps will assist you:
Power cycling the router:
Reset Network Card
Now that the router and the network card are reset, connect the printer back to the wired network and disable the two communication settings. The following steps will assist you:
On one computer remove and readd the printer to the printer list and perform a test print. Wait approximately 10-15 minutes and perform a test print from the same computer. With successful results, remove the printer from the other computers and readd to the printer list.

Thank you very much for the reply. I followed these directions carefully.
Just making sure: After deleting the 922 from my Mac's setup, I presume the proper printer to add back to the system is the "Bonjour multifunction" entry that appears in the "add printer" dialogue? This seems to be the only way for the Mac to know that the printer also has scanning capability.
Regardless, the initial printing attempt was successful. As directed, I waited a while (more than 15 minutes) and tried again. Unfortunately, I am still getting the exact same problem: the system is unable to find the printer. However, as before, if I turn the printer off and back on again it is found immediately and works fine...for another few minutes, until it disappears again.
Note that I have zero other problems on my network, and critically, I can still ping the printer's IP address the entire time with zero missed pings, and can also reach the printer via its embedded web server after the printer driver can't find the printer. So, it's definitely not something obvious like a bad ethernet cable, switch port, Ethernet port on the printer, or what have you.
Any other suggestions? I've been trying to solve this problem on and off for over a year. It's pretty frustrating. Love the printer, but turning it off and back on every time I want to use it is a a real bummer.

It's worth noting that I have exactly zero other problems on my network. Everything works, I have no connectivity problems, machines don't just drop off the network, etc. I've been working on networks for over 25 years and I have a ton of experience troubleshooting--I'm not a noob by any stretch of the imagination.
So, with that said, I carefully followed your directions. However, this has not helped my problem at all. When the printer is first powered up, all the Macs on my network can find and print/scan properly. However, after a few minutes of the printer going idle, all attempts to print result in the following:
Note the "Printer is not connected." message at the top of the window.
It's further worth noting that I started a continuous ping when I powered the printer up, and as you can see, it never loses a ping, even when the Mac driver shows it having gone offline:
I can also browse to the embedded web server in the printer and see the various configuration options, etc. even after the Canon printer driver can't find the printer.
Any advice would be welcomed. I've been trying to solve this problem for over a year. Love the printer...but it's annoying to have to power cycle the thing every time I want to use it.
p.s. I've posted this reply three times now. It keeps getting deleted, which is a liltte suspicous. If you don't have an answer to this query, just tell me instead of deleting my reply.

Wondering if this has been resolved.
I've had the same issue. I'm not sure if this is a spooler service issue, or some MS/Canon security mismatch that someone doesn't want to patch the driver for or what.
I'm a network engineer for what is likely a much larger company than canon, and the bulk of what I do is troubleshoot issues like this with rf guns, Printers of all types, etc from multiple vendors. and not much of what is being listed as possible fixes make a lot of sense. (Other than restarting the PC/Printer/Spooler service)
Do you have an issue with some sort of adapter power saving feature/bug that is dropping the spooler service or locking it up, and then it's not restarting it?

Thank you so much for your post. My hope in putting this problem out there is that maybe Canon could solve it. If not, I hoped others with the same problem would chime in.
The problem remains unchanged and unresolved. You and I are in similar lines of work; I too am a network engineer by trade. My suspicion is that there is some sort of socket in the printer's network stack that just closes after some period of time. However, I have a lot better things to do than take pcaps of this traffic and sort out where it's failing. It's clearly on the printer's end, since I have the exact same problem with 3 different Macs on the network--the printer is there for the first two minutes after it's powered on, and none of the Macs can see it after that. Two of these are desktops with most power saving features disabled, BTW.
I couldn't agree more that the proposed solutions were not related to the problem. However, I dutifully followed them anyway. FYI the final suggestion that the moderators made, which was to call the help line, is something I actually already ran to ground before I made this post. The person on the phone was not able to help at all, and in the end they got to the end of their troubleshooting script and told me to "contact my network provider." Obviously this was not helpful either, given that it's my home lab and therefore I am the "network provider." ;-)
Good luck with your printer...and thanks again.

In their defense, it was probably an MS update that broke their driver. Doesn't excuse them for not fixing the driver, which hasn't been updated since 2016.
I have a Google Wifi router fed by a Spectrum modem. The Google Wifi router has an uplink to an HP 1910 8G switich, which the printer is attached to with a static IP for the printer off the switch. I'm just mirroring a port now and will likely put a raspberry pi on the monitor port running t-shark and run it until it does this again. wouldn't be the first time I've had to figure out a vendor's problem myself, when they won't own it, or can't.
