Abstract
A printing system for printing on a sheet of print media, the system including an electrophotographic printer operable to print on the sheet at a first print speed; and a color printer operable to print on the sheet of paper at a second print speed. The inkjet color printer includes a bidirectional sheet advancer operable to controllably move the sheet along an inkjet printer print path in either of first or second opposite directions, an inkjet pen carriage configured to support at least one inkjet pen and movable in a scan direction transverse to the inkjet printer print path for printing on the sheet, and a registration system operable to register a color image to be printed by the inkjet color printer relative to the black image printed by the electrophotographic printer. The registration system includes an optical sensor supported by the inkjet pen carriage for movement with the pen carriage along the scan direction.
