Mx920 Wireless printing problem

[slashmon1]

I have just bought an mx920, beautiful printer I may point out, it worked well for the first two days but I cannot print as of today, I connect to the printer wirelessly and all my computers are Macs.

The printer is connected to the network properly and my computer shows that it has an active connectiong, but when I click print the printer goes to "in use" and then goes offline, and the Print Que says "Printer not connected" 

I've tried connecting the printer to the network again, and I have restarted the printer along with my computers but it still wont work. 

Please help

MENU > SETUP > DEVICE SETTINGS > LAN SETTINGS > CONFIRM LAN SETTINGS > PRINT LAN DETAILS

I think this is what you're looking for, hope it helps.

Joseph, if the printer has its own screen it can display its address if you use the screen & menus to navigate to its wireless settings. I assume it can also print out its address, using one of the menu options.

I'm not sure whether NoWake2000's instructions are accurate.  I think you're looking for the wireless settings, not the LAN settings.

entered a value in the location....

result - still failed.

@elmatic0ne, thanks for trying it. (I'm surprised more people haven't tried it and reported their result.)  My printer has been behaving fine ever since I tried it.

I'm sorry to hear that entering a value in the Location field didn't work for you.  I'll assume that after entering the value, you also clicked on the Save button, but if you're unsure whether you saved it you might check the printer's Settings webpage again to make sure the value you entered is still there. 

I'm also assuming your problem is the same one that was cured for me by entering a value in Location: after hours of inactivity, the printer was no longer available. (In other words, the computer behaved as if the printer wasn't connected, and displayed an error message that said that.)  Some people who have posted comments in this thread have had different wireless connectivity problems.  So it might be helpful if you confirm the assumption by describing your printer's wireless problem in your own words.

Here's a diagnostic question that may help your troubleshooting: Is the printer's webserver accessible by your computer's web browser while the printer is unavailable for printing?  In my case, it was accessible.  If it's not accessible in your case, I think it's a hint that your wireless connectivity problem has a different cause... and the cause isn't necessarily the printer.  What other troubleshooting steps have you tried?

None of these solutions have worked for me.  IMac w Yosemite OS.  Local Area Network.  Computer connected to printer through USB and both connected to TIme Capsule as the airport stations. 

I have powered down, downloaded latest updates and there is no firmware available on canon site...VERY FRUSTRATING - it essentially stopped working for me 4 months ago after working well.

@Another_Victim,

Could you please explain two things?

1. Where did you find the printer's  IPv4 address? and.

2. What value did you enter?

Thanks in advance for any assistance.

@Another_Victim

strange thing - turned on the printer after 24 hours and connected without issue. Even had location listed that I entered the previous night. So I thought, great it finally works!

a few hours later, went back to it and no connection at all. Tried this morning, no connection. 

I can only connect to the printer web interface when it is actually connected.

Funny thing is, I see the printer mac address in "wireless clients" but not listed in dhcp table. Every other device connects without issue, once again - without issue. Why would a printer be any different. I have family and firends come over and use my wifi connection with their laptops, tablets and cell phones - they leave and come back after a few weeks and their device recalls the connection right away. 

In any case, I'll try one more time tonight - if not then bye bye canon.

There are several ways to find your printer's IP address:

1. The Canon printer's touchscreen can display (or print) it. (Explore the printer's menu to find the Wireless settings.) 

2. Your router's built-in webserver can display the addresses of all networked devices.

3. Your computer probably has a network tool that can display the addresses of all networked devices.

The value I entered into the Location field in the printer's webserver's Settings webpage was:

 Home

I doubt it mattered what value was entered into the Location field; I assume that what matters is that it not be left blank.

I don't recall whether I mentioned the importance of setting your router to assign a static IP address to the printer.  A "static" address is a constant address.  The alternative (which is probably the router's default setting) is for the router to assign a "dynamic" IPaddress, which can be different depending on the other devices you occasionally connect to your network, such as smartphones and portable computers.  It's possible that Canon's driver software in the computer is clever enough to find the printer even if its IP address changes, but I wouldn't bet on it, and it's easy to set the router to assign a static address.

@MMGates, how about clearly describing your problem, and which of the many troubleshooting ideas posted previously in this forum thread you've tried? Also, it's unclear what you meant by "connected through USB" since this forum thread is about the printer losing its wireless connection... perhaps it would help if you express yourself using complete sentences.

[Another_Victim]

@eImatic0ne: Have you set your router to assign a "static" IP address to the printer? Does the printer still have the same IP address as it had when it was working? You should use the printer's built-in touchscreen menu to display its wireless settings both when it's working and when it's not working, to see if anything is different.

A changed printer address could explain why you also weren't able to connect to the printer's web server.

If family and friends are occasionally bringing wifi-accessing devices such as smartphones & laptops within range of your wifi router, it might affect the address your router assigns to your printer, unless you set your router to assign a static address to your printer.

The only way a printer is different from other devices, I think, is that computers and laptops and smartphones need to know the printer's address (and its other properties) in order to use it to print (or scan).
