C. Flow of Image Signals

1. Flow of Image Signals from the Printer Board

The PDL data from the host computer is processed into printing images on the Printer Board and sent

to the Protocol Controller PCB as image signals.

The image signals move through the Protocol Controller PCB to reach the CORE/IP Board. After res-

olution conversion, the image signals move to the Image processor PCB for printing.
