@stratman, why would I need a list of error codes, when my printer is quite capable of generating its own list especially for me...
Anyway most of Canon error codes are so erroneous there’re usually meant to scare the bejesus out of the owner into thinking they’ve broken their beloved printer...
@The Hat -- the error codes are becoming anachronistic, a throwback to the days when repairs were actually done on printers and your local repairman fed his family for another day.
However, I would think the error codes still serve a couple purposes for Canon, such as facilitating warranty repairs and technical feedback for hardware and software update designs.
Anyhoo, the aggregated list is a curio I thought some fellow printer nutz would like.
