Pixma MX490 Keeps Cycling

[elstx61]

Canon Pixma MX490 powers on and goes through initialization, then powers back off.  Keeps repeating the process as long as it's plugged in.  Buttons are non-responsive.

Solution but only if you don't require any online/web services from your printer (cloud?): To begin, I used my IP address, changed a bit for this fix. Get it at computer control panel--view network status--connections (hyperlinked, gives wifi status when clicked)--details button--write down IPv4 address. Unplug printer while it's off. Unplug router. Plug printer back in and it will start. On mine & I think most, press "tools" button, gives you setup menu. Use arrows to move thru selections and OK to make selection. Arrow thru to web service setup, OK. Arrow to DNS server setup, OK. Arrow to manual setup, OK. I had all zeroes here, but used my IP address to fill in but changed last 3 to 006, but I think any number will work, OK. (My wireless requires key/password and I hope yours does too, but it's wrong anyway so...) Then select NO option. Printer will do its thing. When menu comes back, I think press the tools button again to exit. Then plug router back in. It will take awhile for it to reboot and your wireless service to return. When it does, you can wireless print/work again. On and off creates no issues. In effect, this disables your printer's capability of connecting to the web, but does NOTHING to your local wireless.

I had this problem to. This problem can rectified by preventing your printer from having internet access. You can do this through your router if it has the option to manage devices within the router gui. Just block the printer from the internet. While this will prevent your printer from reaching the internet it will still allow LAN access so your home devices can still print to the printer.

My MG7520 still isn't working... has Canon seriously not been able to find a solution in 4 days? It's extremely frustrating...

Canon is now offering a firmware update to fix this (see below) but if you want a fairly easy quick fix (and these will be my last posts on this, I have a headache!):

I have a Canon Pixma MX 492 and it keeps cycling over and over again, I tried reinstalling drivers, hooked up direct via USB, and NOTHING WORKS! As a graphic designer CAN'T GET MY WORK DONE AND AS A RESULT AM HAVING VERY UNHAPPY CLIENTS!

WHAT IS THE FIX!!!!

[SamS1]

You can find the workaround (disables web access to the printer but not wifi) by just reading the through the posts at the beginning  of this thread.

Doesn't work

Make sure you disconnect the printer from the internet (either through router settings or just turn off the router) and turn the printer off (unplug the power cord), then plug it back in, adjust the DNS address in the Web Services menus and turn the router back on.
