What to try

If the cover was opened during printing (1203): pull out any paper left inside slowly with both hands, close the cover and press OK. Canon warns not to open or close the cover during printing.

Write down the exact code before you do anything else — similar-looking codes often mean completely different things.
Power the printer off, unplug it for a couple of minutes, then power it back on. A surprising number of transient errors clear here.
Open the covers and check for paper scraps, packaging material, or anything blocking the carriage.
Check the cartridges or tanks are genuine, correctly seated, and not empty.
Confirm the printer is plugged directly into a wall outlet, not a power strip or extension lead.
Check your model’s own manual — codes are model-specific, and the manual is the authority for your machine.
