Formatter system
The formatter coordinates the major systems. It is responsible for the following tasks or actions:
●
Formatting and controlling copies
●
Receiving and processing print data from the product interface
●
Monitoring the control panel and relaying product-status information
●
Developing and coordinating data placement and timing with the print engine
●
Communicating with the host computer through the bidirectional interface
●
Communicating fax data to and from the fax card
The formatter receives print data from the 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 embedded Xtensa processor operating at 240 MHz.
Fax card
The fax card provides the required safety isolation, signal coupling, and global impedance matching and
analog to digital conversion of incoming and outgoing fax data.
