1.5.1
C205 MAIN Board
The C205 MAIN board is a Main controller board. The primary functions of this board are receiving
print data from the host, generating the print image (Main), and sending the print image to the
engine controller via the Main interface. A 32-bit 20 MHz RISC CPU MB86930 (SPARKlite)
(location: IC15) is used, and the following memory chips and custom ICs are assigned to the 4 GB
memory space.
