Hi lpilot.
Directions for resolving the 6A80 error also apply to the 6A81 error. Open them in a new window or tab: https://support.usa.canon.com/kb/index?page=content&id=ART133530
If that doesn't correct the error, then the printer will need to be replaced. If you are located in the U.S., I can offer the Canon Upgrade Program, a one-time discount on the purchase of a replacement. If you're interested, more information is available through our phone-based Canon Direct agents at (866) 443-8002.
