PAPER CURL COMPENSATING DEVICE FOR A ROLL FUSER John Trainor

Proposed Classification
U.S. C1. 271/161 Int. C1. B65h 1/00

This disclosure relates to the curl problem that roll fusers create in copy paper. The problem of curl is solved by intentionally introducing curl into the copy paper, the direction of the curl being opposite to that which will subsequently be induced into the paper by the roll fuser.

To this end, a paper tray 10 is provided which has a bottom wall 12 which is curved in order to bias copy sheets 14 as shown. This arrangement induces positive curl into the copy sheets 14 which is subsequently removed by the action of a roll fuser 16 to thereby produce fused copies with a minimum of curl.

The image fused to the copy sheets is formed thereon by means of a conventional xerographic image forming apparatus generally indicated at 18.
