Abstract
Standard, unfixed electrophotographic images are transferred from a photoconductor drum (5) to paper (7) at a nip location with a transfer roller (3). The paper remains in contact with the transfer roller until it is positioned under a ink jet printhead (9), where a second image, typically color highlights, is printed. This configuration requires no additional registration of the two images. The ink jet printhead may be charged to repel stray toner which might clog its nozzles. The transfer member may be a belt or may be large enough to permit movement of the paper at the higher speeds of electrophotographic at the transfer station and at the lower speeds of ink jet printing when the paper is at the ink jet printing station.
