Open the CIPO recordAbstract From the Canadian patent
An electronic printing system comprises a substrate, controllably transported through the printing system past a plurality of print heads and print stations in sequence, to generate a printed image. The print heads are mounted on a swing arm mechanism to allow rotation from a print-ready position into a service position. The system is created from simplex print modules and is capable of multi-color and process color duplex printing without turnbars between print stations. The system is configured so that additional print stations can be added to the printing system without adding substantially to the length of the system.

Why it's free to use
- Filed June 17, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 17, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 17, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
