Formatter system The formatter is responsible for the following: controlling the document scanner formatting and controlling faxes formatting and controlling copies receiving and processing print data from the printer interface monitoring the control panel and relaying printer status information developing and coordinating data placement and timing with the print engine communicating with the host computer through the bidirectional interface The formatter receives print data from the bidirectional Extended Capabilities Port (ECP) mode interface or USB interface and converts it into a dot image.
The ECU synchronizes the image formation system with the paper feed system and signals the formatter to send the print image data. The formatter sends the print image data (dots) in the form of a video signal and the printing process begins. Central processing unit The formatter incorporates an MCF5202 custom microprocessor operating at 35 megahertz (MHz).
