Open the CIPO recordAbstract From the Canadian patent
A method and apparatus for positioning paper in a feed path by providing continuous feedback of copy sheet registration parameters is disclosed. More specifically the present invention is directed to a system which compares measured sheet registration information with an ideal value stored in a microprocessor. These measured registration parameters are averaged and pertinent information is fed back to the control system of the copy sheet registration device. The information that has been fed back is then used to adjust the orientation of subsequent copy sheets, thereby allowing for ideal placement of the copy sheet onto the photoreceptor for successful transfer of a developed image.

Why it's free to use
- Filed July 16, 1997 and granted September 11, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 16, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 16, 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.
