Open the CIPO recordAbstract From the Canadian patent
A system for flushing ink residue from a fluid system is provided for use with a continuous ink jet print station. Ink is rapidly drained from the fluid system, and the fluid system is refilled with a flush fluid. The flow of flush fluid is directed through all fluid system components which normally contain ink. Subsequently, the flow of flush fluid can be diverted to a waste tank rather than re-circulated into the ink tank.

Why it's free to use
- Filed December 13, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 13, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 13, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
