Abstract
A printing system for printing multiple colors on a sheet of print media includes an electrophotographic printer having a photoconductor drum and a transfer roller configured to interact in co-rotation with the drum during transfer of a color image plane from the drum onto a sheet of print media passed therebetween. A paper drive sheet feeder system is included which has a grit shaft extending generally transverse of a paper travel path, a first pinch roller configured to interact in co-rotation with the grit shaft along a first edge of a sheet of print media, and a second pinch roller configured to interact in co-rotation with the grit shaft along a second edge of the sheet of print media. The grit shaft is driven in rotation to drive the sheet of print media along a bidirectional sheet travel path such that a plurality of different colored image planes is superposed onto the sheet of print media in accurate registration therebetween. A method for printing multiple colors is also described.
