About the EB-34
The EB-34 adds computer connectivity and highly efficient PostScript and PCL printing ability to the Pro 8220S/
8210S/8200S/8120S/8110S/8100S and Pro 8220/8210/8120/8110.
With the EB-34, 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-34 from supported client computers on the network.
The EB-34 ships with software preinstalled so that customers can use it immediately. However, as part of servicing the
EB-34, you may need to reinstall software.
How the EB-34 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-34 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.
