Canted wheels drive a document across a document glass and against
In a copier, documents entering a document glass out of alignment, for
example, position A, must be aligned in a standard position B, in registry with
copier gates (not shown). Canted drive wheels press against the glass and
rotate on shafts turned by a drive motor. The center of each wheel falls on a
center line parallel to the registration edge.
Misaligned incoming documents are driven by the canted wheels against the
registration edge and across the glass into registry with the gates. The canted
wheel angle (Phi) falls between 2 Degrees and 20 Degrees nominal direction of
paper travel. Typical wheel materials are rubber, silicone and urethane foam.
