These Canons are designed with a printhead we can remove for inspection, unlike the later CLI-X tank models, where, sadly, they took notes on HP's final run of 564-based units on integrating that part. Given the printer's age, it's more of a wildcard than it was a few years ago, when it was usually the ink tank and not the head. Try to [link|https://support.usa.canon.com/kb/index?page=content&id=ART143852|reseat the printhead first], clean it in hot water if need be and there's residual ink on the contacts inside the unit or the head contacts on the back. If the issue remains, try a complete set of ink tanks if the chips are dirty/intermittent, especially if you've reseated it a few times and the issue remains; could be a bad chip. It doesn't have to be OEM with Canon, but you WILL get nagged during the installation to clear the ink monitor alerts.

If that isn't it, check in the print mech for any loose paper and shreds that may be tripping the sensor; [link|https://support.usa.canon.com/kb/index?page=content&id=ART137155|see here to see how to unjam this series|new_window=true]. If there's no trace of paper in the path and you have checked multiple times (and confirmed the path isn't hiding anything!), the sensors may be at fault. It may or may not be easily repaired on this model; sometimes you can take the sensors out and clean them with isopropyl alcohol, and that's enough, but sometimes they're just shot.

***NOTE: If there is ink near the contacts or the head looks messy overall, clean it in hot water if need be, especially if there's residual ink on the contacts inside the unit or the head contacts on the back.***

Canon does say there may be leftover packing material... but given the age, this is probably doubtful at best. It's worth checking, but don't spend too much time on this.

The last thing you can try is to let it sit unplugged for ~5 minutes (which may very well be enough) but go for at least 30 minutes if you can to be sure. If this doesn't help, it's a major failure like the mainboard. Not worth fixing that.
