Over the past two days, an increasing number of owners of certain Canon Pixma printers have reported that the devices either won’t turn on at all or, once turned on, get stuck in a restart loop, turning on and off for as long as are plugged in. Edge Reader Jamie flagged us posts on Reddit regarding the issue and Canon’s own support forum, citing issues with models such as the MX490, MX492, MB2010 and MG7520.
Some believe that their problem is caused by a software update that Canon sent to the printers, but this has not been confirmed yet. In response to a request from The edgeSenior Director and General Manager of Corporate Communications Christine Sedlacek said, “We are currently investigating this issue and hope to provide a resolution shortly as customer satisfaction is our top priority.”
Until there is an official update or fix, some people in the forums have found that disconnecting printers from the internet is enough to prevent them from restarting, with control still possible via USB.
To get printers working while maintaining your internet connection and their connection to local network devices, a customer response on Canon’s support forum suggests a method that many people say has worked for them. If you’re experienced with network configurations, DNS servers, and IP addresses, it might be worth a try, but for most people I’d recommend waiting for an official solution.
To follow their steps, then after taking your internet connection offline, turn on the printer, go to its network settings and under web service configuration select DNS server configuration and choose manual configuration. In this section, enter an internal network address (192.168.XX, with numbers replacing X that are not used by other devices on your local network), press “OK”, then press “no” for a server Secondary DNS. This keeps the printer connected to your router without accessing the wider internet, and for some reason was enough to prevent devices from rebooting.
