Principle of Operation
The IP-422/423 includes 64 MB of RAM as standard so that it can rasterize image data for subsequent
pages while it is sending the rasterized image date for the current page to the print engine. The memory can
also be expanded to accommodate the processing of very complex print data. This system means that the
print engine can comfortably process print jobs consisting of many pages without interruption, to achieve effi-
cient and effective printing.
The print controller system software runs on VxWorks from Wind River and is included in the standard Com-
pact Flash memory.
The scanned data is sent to computers via the standard Ethernet network interface.
The transmission and reception of scanned data between the print controller and the print engine performed
by the built-in engine interface (video interface).
In addition, the serial interface provides access to the system in the print controller.
