Canon Support Code 1683: Remaining ink level cannot be detected (refilled tank)
✅ Usually fixable yourself
The printer cannot correctly detect how much ink is left in a tank, and the lamp on the tank flashes. This happens with a tank that was once empty.
What to try
- Replace the ink tank and close the top cover.
- If you choose to keep printing, Canon says you can turn off ink-level detection by holding RESUME/CANCEL for at least 5 seconds.
- Canon warns that printing with a once-empty tank may damage the printer and that it is not liable for damage caused by refilled tanks.
When it needs a technician
Not a repair issue. Replace the tank.

First steps for any printer error
- 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.
