Support Code 1686 Appears - TS3720

Article ID: ART184688 | Date published: 04/02/2024 | Date last updated: 04/03/2024


An issue with one of the ink cartridges has been detected.



The 1686 support code signifies that the printer has detected an issue with one or more of your ink cartridges.


What to Do

If you intend to PRINT or COPY, you should take one of the following steps:

- For each ink cartridge identified by the printer as having an issue, disable the function that detects the level of ink remaining by pressing the Stop button on the printer for at least five (5) seconds and then releasing it.

If, due to individual usage factors, there is some residual amount of ink in the cartridge(s), you will be able to PRINT or COPY until the remaining ink is depleted.

Please note that image quality may be diminished if you PRINT or COPY when there is little ink remaining in the cartridge(s).


- Open the cover, replace each ink cartridge identified by the printer as having an issue, and then close the printer's cover.

Canon recommends the use of new, genuine Canon ink cartridges for optimal image quality.
