Abstract
A full color copier having an inkjet printer includes a controller and algorithm for switching automatically intra page between one of two independent high speed carriage velocities and between one of two independent pen firing frequencies for maximize throughput relative to low ink density and high ink density graphic images to improve print quality images having densely inked areas by substantially reducing ink pen starvation, droplet trajectory errors, and fuzzy text edges.
