Canon ImagePrograf Pro-300
Signature Edition
We are currently working on Refill Kits for this model. Expect release sometime in December 2020, the kits will be ready complete with some excellent custom ICC profiles.

However, since no resetter is available at this time,
we highly recommend that you acquire a second set of CANON OEM tanks for the Pro-300. These will be invaluable when refilling this printer.

Also
DO NOT DISCARD the orange storage clips/stoppers that came with the tanks. Again these will be necessary in the future.
