About the E-35A
The E-35A adds computer connectivity and highly efficient PostScript and PCL printing ability to the Pro C7200SL
printer.
With the E-35A, customers can use the printer as a PostScript printer and scanner. Once it is connected to the printer
through the network, customers can print to the E-35A from supported client computers on the network.
The E-35A ships with software preinstalled so that customers can use it immediately. However, as part of servicing the
E-35A, you may need to reinstall the software.
How the E-35A operates
When a customer prints, the motherboard and printer interface board process image data. The printer interface board
is a custom board and allows the E-35A to communicate with the printer. The CPU controls the transfer of image data
to and from the motherboard and runs the PostScript interpreter. DIMM holds 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 printer
interface board. The raster data is sent to the printer, which then renders the image on paper at maximum speed.
Warning: The WARNING icon indicates a warning concerning operations which, if not performed correctly,
may lead to death or injury. To use the E-35A safely, always pay attention to WARNING icons and messages.
Caution:The CAUTION icon indicates a caution concerning operations which, if not performed correctly, may

Important: The IMPORTANT icon indicates operational requirements and restrictions. To operate the E-35A
correctly and avoid damage to the E-35A or other property, always pay attention to IMPORTANT icons and
