Canon imageCLASS MF632Cdw connected to network but not recognized

theohster — Wed, 03 Oct 2018 06:37:44 GMT

I am having a new and somewhat strange problem with my printer. It is connected to my network -- it has an IPv4 address (192.168.1.5 when connected via WLAN, 192.168.1.20 when connected by Ethernet). The printer's display shows that it is connected to my network. However, it does not appear on my network. For example, neither my laptop nor my iPhone can "see" the printer, and when I log into my router it does not appear as an attached device. Printing does not work...unless I connect it to my laptop with a USB cord.

However, and this is where it gets strange, I am able to use Google Cloud Print with it. So the printer appears to be connected to the internet, even though it seems to be invisible to my local network.

I attempted a factory reset, but that did not solve the problem. Any suggestions would be greatly appreciated!

I also have this issue. Did you ever get it resolved and if so, how?

Simiiar issue: can't see the printer!

Background Information:

Mac OS 10.14.2 mojave. Yes I have the lastest Driver installed

Same printer MF642Cdw only on WIFI, no hardwire connection

All the other household MAC's can see the printer and print!

Yes I've re-started the printer several times

The Router is dual 2.4 and 5 ghz

the router see's the printer and assigned a IP address. Same as the IP address on the printer.

I can logon to the printer from a brower. All looks good.

My computer (the one in question) is on the same WIFI network.

When I try to add the printer, with systems perference, it does not show up.

Before I upgraded to 10.14.2 I was able to use the printer. Now nothing.

All the other MAC are 10.14.1 OS

I've also added another Canon Printer MP560 series without any issues.

Your Thoughts!!!

Solved the problem!!

MAC will not "see" the printers if the firewall is turned on.

Go to SYSTEM PERFERENCE, Security and Privacy, Firewall, OFF

RE-start the computer, Go to System perfernence, printer&scanners, click the lower left "+", wait a few minutes and your network WIFI printers will come up, complete the installation of the drivers etc and your done!

Good Luck

If you have to turn off ANY computer's firewall to get it to see the printer, the software developers for the device are brain-dead for asking customers to turn off one of the MOST important security features available. I repeat, that would be brain-dead of them to do so. (Not that it doesn't happen. I've had DSL modems that wouldn't let me do FTP transfers w/o taking my firewall down!!!! Threw that one in the trash!!!!)

For what it's worth, I did the initial configuration of my MF644Cdw printer with a Mac and was able to print with it, no problemo, all while my firewall was running. So it WILL print with the firewall up & running.

Still, I encountered this issue a week later and verified that I could see the printer's IP address on the LAN. But still, my Mac could not find the printer. Solution: System Preferences>Printers & Scanners>selected the "Canon MF642C/643C..." in the left hand pane, clicked the "-", then clicked the "+" and selected the Canon driver for it. After that it found the printer with no problem.

Technically, this is not a fix but rather a workaround. Will have to see how often this reoccurs. If it happens again, I'll see if this is a problem in Windows as well.

Re: Image class 644cdw. This printer has given me a headache since the day I purchased it. It intermittently puts itself offline and won't print. 2 weeks ago I waited for 2 hours to speak to a customer Service rep and we did a factory reset. The printer stored the correct IP address during the call. Since the call with the Rep. 2 weeks ago I have done a factory reset 3 times. The
latest reset today. Now not even a factory reset will force it to remember the correct IP address. So it's essential an expensive piece of junk. Any other suggestions before it gets returned?

Well I'm sure this will change as soon as I hit the "Post" button but since my first post, have not had any problems with the printer. Fingers crossed that it stays up on the network going forward.

how did you perform a factory reset of this printer ?

I am unable to do it or find those instructions. Appreciate your help.

For the Canon ImageClass MF644CDW, press Menu, Management Settings, Initialize all data/settings. Accept the prompt stating everything will be deleted (essentially a factory reset). Even resetting to factory default no longer works on my printer so there it has to be defective.

Hi peebz7.

Is the MF644Cdw connected to your network using an Ethernet connection, or using WiFi? If by WiFi, does your router support 5G?

Also if using WiFi, are you using a WiFi hotspot as the access point, or a standard wifi access point / router / modem?

Are you able to open the printer's remote UI? If the remote UI is not accessible, then your router is not allowing the printer and computer to communicate. If the remote UI comes up, then the printer is being allowed to communicate, and some setting on the computer is blocking the printing capability.

Which operating system type and version is running on the computer?

Hello. I have been having the exact problem detailed for the last couple months. It is super annoying. Yesterday after trying to get it to print for an hour, all of a sudden it just started printing on it's own. It printed my document plus about 3 test pages haha.

So I had tried everything, and can see the printer from the remote UI. It never even sees the jobs come in. Firewall doesn't matter, whether it works or doesn't work doesn't depend on it, I have found.

So this morning, frustrated after reading the responses I tried something that WORKED. I deleted the printer from Printers and Settings. There were two listed, one was U2 and one was U4 after the name. Those are the ones from Cannon, so I figured they were the best to use.

I then told windows to add the printer. It put in the new driver which does not have the U2 or U4 after it but does have the right printer type as the name. I think this driver is from windows. I sent my job to the printer and boom, it worked instantly!

I think what we have here is a print driver with a bug that goes out to lunch after a while.

I would try deleting and reinstalling the print driver like I did. Worked for me today. I wonder if it will keep working?!

The only thing that worked after trying some of these suggestions was to delete the printer from my preferences and then add it back:

>SYSTEM PREFERENCES

>printers and scanners

>Highlight "CANON"

> Hit the (-) button on the left corner

Then hit the (+) button to reinstall Canon

I had this problem for 2 months on Mac OS 10.15.3. and ImageClass LBP612Cdw, with the latest printer driver and updated printer firmware.

The printer was fine sometimes, other times it could not be found.

Deleting it from the list of printers did not help -- when I went to add it again it wasn't found. Wireless Network Status was OK, so it was connected to WIFI.

This finally worked for me:

Menu : Preferences : Network : Wireless LAN Settings : Power Save Mode: OFF

It hasn't given me trouble since.

I have been experiencing the same problem from my Mac (periodic drop of connection to printer), but my Windows and Linux systems work fine with my MF642Cdw. This leads me to suspect a device driver issue on the Mac. Previously I solved this by completely reinstall the printer driver after dropping the printer definition on my Mac. I decided to try something different this time.

Long story short, here's what worked. Instead of using the "+" button to auto-discover and add a printer (which the Mac was not able to rediscover my printer), I chose the tab "IP" add the printer by IP address. On the printer's mini-display screen, I found the printer's IP under Status Monitor (lower right corner) -> Network Information --> IPv4. Using that IP address in my Mac's Add printer / "+" function, I was able to discover the printer instantly and add it. After printer addition, it's easy to rename the entry from IP address to a normal name. Printer then worked without further issues. Keeping my fingers crossed and hope this lasts.

thanks 39784. i was able to make the printer work using the a fixed IP address.

the big question is HOW DO MAKE THE SCANNER WORK?

it can't be found in the ADD PRINTER/SCANNER menu under PREFERENCES.

this is really a lousy MF AIO. it works fine on my son's Win10 Dell but doesn't work consistently with Macs. 😞

I've had this exact issue repeatedly since I bought the MF741C a year ago. So frustrating to have to continually delete and read the printer on my MAC. There has to be a simple solution to this Cannon.

nofrets — Wed, 08 Dec 2021 15:47:44 GMT

Yeah, I’ve reinstalled my drivers more times than I can count. It’s really a lame technical “solution“ and the latest pass leaves me without a scanner for my Mac. Scanning workaround is twofold: a) put document in feeder and scan directly to USB flash drive, then copy the scanned file to my Mac, and b) delete Canon from my future purchases consideration list. I’ll change my mind if they cease the Mickey Mouse &@#%*!!! and release consistent AND KLUDGE-FREE product software.
