Background
What this message usually means
Canon uses support code 1680 when the TS5000 series detects that the installed ink tanks do not match their expected positions. This is usually an installation-state problem after replacing ink, not a deeper mechanics fault.
Before the message
What users usually notice first
Messages like this often appear after the printer fails one of its normal startup, supply, or paper-path checks and cannot return to ready state cleanly.
Diagnosis
Likely causes
An ink tank was inserted in the wrong color position.
The printer is reading a recent cartridge swap that was completed incorrectly.
One or more tanks were reseated in a rush and ended up in the wrong slots.
Service
When service or replacement is more likely
- -Treat this as a cartridge-position mistake first, not as a printhead or mainboard failure.
- -If the LCD also shows a recognition or install error, fix the physical tank positions before chasing the other code.
Avoid wrong turns
Common misreads of this message
- -Treating the message like a confirmed failed part instead of a support clue about which system has stopped the printer.
- -Assuming any supply-related wording means the next step is automatically to buy a cartridge, toner, drum, or printhead.
