About the EB-32
The EB-32 adds computer connectivity and highly efficient PostScript and PCL printing
ability to the Pro 8120S/8110S/8100S.
With the EB-32, customers can use the copier as a PostScript printer and scanner. Once it is
connected to the copier through the network, customers can print to the EB-32 from
supported client computers on the network.
The EB-32 ships with software preinstalled so that customers can use it immediately.
However, as part of servicing the EB-32, you may need to reinstall software.
How the EB-32 operates
When a customer prints, the motherboard and copier interface board process image data.The
copier interface board is a custom board and allows the EB-32 to communicate with the
copier. The CPU controls the transfer of image data to and from the motherboard and runs
the PostScript interpreter. DIMMs hold image data during printing.
The interpreter rasterizes the page description file and compresses the image pattern into
memory using compression technology. The interpreter outputs the compressed raster data
through the image frame buffer memory to the copier interface board. The raster data is sent
to the copier, which then renders the image on paper at maximum speed.
