How the E-41 operates
The E-41 enables the customer to use the copier/printer as a high-performance, networked
PostScript color printer and scanner. Users at the customer site can print to the E-41 from
networked Windows computers, Mac OS computers, and networked UNIX workstations
running TCP/IP.
The E-41 custom-designed boards and system software provide efficient image processing and
printing controls. The main functions of E-41 components and software are described in the
following paragraphs.
The E-41 uses the motherboard and a custom video board to process image data for printing
and scanning images.
The motherboard includes an Intel Core 2 Duo E8400 3.0GHz CPU that controls the image
data transfer to and from the motherboard and runs the interpreter. The interpreter rasterizes
the page description file and compresses the image pattern into memory using compression
technology.
The interpreter outputs compressed raster data through the image frame buffer memory to
the E-41 video board. The video board decompresses the image data and sends it to the
copier/printer through a crossover copier/printer interface cable connected to the upper RJ-45
on the E-41 back panel. The raster data is supplied to the copier/printer, which then renders
the final image on paper at full rated engine speed.
High-speed DIMMs (dual in-line memory modules) on the motherboard hold the image data
during printing. The E-41 is configured with two 1GB DIMMs for a total of 2GB of
memory.
When Fiery Scan uses the copier/printer as a scanner, the E-41 acquires RGB (red, green, and
blue) image data from the copier/printer, stores it in memory, and transmits it to the
computer that requested the scan.
