Hello, I'm Wes, and I'll be assisting you today.
Error 1403 is a problem with the print head overheating. The problem is not easily fixed and will require a new print head from Canon.
The problem is due to the malfunctioned print head and will require a replacement print head. Check first to see if you printer is under warranty that way it can re replaced. They cost about $50 and sometimes better to purchase a new printer for close to that price. If you would like to purchase the replacement print head you can get one here:http://www.usa.canon.com/cusa/professional/standard_display/support_pro/pro_service-parts
