Until there is an official update or fix, some people in the forums have found that disconnecting the printers from the internet is enough to keep them from rebooting, with control still possible via USB. In response to an inquiry from The Verge, corporate communications senior director and general manager Christine Sedlacek said, 'We are currently investigating this issue and hope to bring resolution shortly as customer satisfaction is our highest priority.'

Some believe their problem is due to a software update Canon pushed to the printers, but that hasn't been confirmed yet.

The Verge reports: Verge reader Jamie pointed us to posts on Reddit about the problem and Canon's own support forum, citing problems with models including the MX490, MX492, MB2010, and MG7520.

Over the last day or two, there have been a growing number of reports by people who own certain Canon Pixma printers that the devices either won't turn on at all or, once turned on, get stuck in a reboot loop, cycling on and off as long as they're plugged in.
