That error would point to a problem with the print head in the MB2320 or a problem with ink getting to the print head. In this situation, you can try unplugging the printer from the power and letting it sit for about 20 minutes to see if the error is gone once you plug it back in and turn it on. You can also check the ink tanks to see if they are properly seated in the printer. The issue could also be caused by an empty ink tank or some third party tanks can cause ink flow issues and produce the error. You can try replacing any cartridges that might be causing the problem. If that does not resolve the issue, it looks like the printer needs service. You can log into your MyCanon account using the link Here to check your available service options.
