Epson scanners are the best of the breed for this, which is why the firmware bombing made me so angry. *I have this for high detail album artwork, and photos.
Frankly, I’m happier with my SJ Pro 2500 f1 and Perfection V39* then the printers. These often hard stop even for scanning with the waste ink errors!!! It wasn’t a chance I would take willingly. Before I got a dedicated scanner with an ADF (necessity, thanks to Epson “security updates” - aka clone cartridge blocking firmware) and HP Dynamic Security (not as bad on the LJ series, but the Deskjet and OfficeJet dynamic security machines get more frequent updates), this class of warning was grounds to retire a Canon printer even as a scanner. A new set of pads can total out the printer (or it requires a lower base), or time you can spend removing the pads but either way, you often need to do a full disassembly on the Canon models with integrated pads. The issue with repair is parts cost, or time.
This warning (more cryptic variant) is the semi common error - other Canon models will tell you outright.
