Formatter system 55
Formatter system
The formatter is responsible for the following:
!
controlling the optional copier/scanner
! 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 Universal Serial Bus (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 Coldfire V3 microprocessor
operating at 90 MHz.
RAM
! One bank of Non-Volatile RAM (NVRAM) stores parameters.
! Dynamic random access memory (DRAM) provides temporary
storage of copy, scan, and print data.
Parallel interface or Universal Serial Bus interface
The formatter receives incoming data through its bidirectional ECP or
USB interface. This interface provides high-speed, two-way
communication between the printer and the host, allowing you to
change printer settings and monitor printer status from the host
computer.
