How to Perform a Hard Reset on a Canon Printer

Turn off your computer and wait for it to shut down completely. Then, push the power button on the Canon printer off.
Remove the power cord from the back of the printer. After the power cord has been removed, remove the USB or parallel cable that runs from the printer to the computer. Remove the cable from both the printer and the computer.
Plug the USB or parallel cable in to the back of the printer. Make sure the cable is securely seated. Pull on the cable to make sure it is not loose. Connect the other end of the cable to the computer.
Turn the power button on the printer back on. Wait a few minutes for the printer to power up, then turn the computer back on.
Log on to the computer and click on the 'Start' button. Choose 'Control Panel' from the menu and select 'Printers and Faxes.' Double-click the Canon printer and click on the 'Printer' menu. Select 'Properties' from the menu and click the 'Print Test Page' button to send a test page to the printer.
