In the past two days, there have been a growing number of reports from 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 are connected. roadside reader Jamie pointed us out posts on reddit about the issue and Canon’s own support forum, citing issues with models such as the MX490, MX492, MB2010, and MG7520.
Some think their problem is due to a software update that Canon pushed to the printers, but that hasn’t been confirmed yet. In response to a question from The edgeCorporate Communications senior director and general manager Christine Sedlacek said, “We are currently investigating this issue and hope to provide a resolution soon as customer satisfaction is our top priority.”
Until there is an official update or fix, some people on the forums have found that disconnecting the printers from the internet is enough to prevent them from rebooting, while still allowing operation via USB.
To keep the printers working while maintaining your connection to the Internet and their connection to local network devices, one response from a customer on Canon’s support forum suggests a method that many people believe 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 fix.
To follow their steps, after taking your internet offline, turn on the printer, go to the network settings and under Web service settings select DNS server configuration and choose manual installation. In that section, enter an internal network address (192.168.XX, replacing numbers X that are not used by other devices on your local network), press “OK” and then press “no” for a secondary DNS server. This will keep the printer connected to your router without access to the wider internet, and for some reason this was enough to stop the devices from rebooting.
