2-1-3. Main PCB
The SH-3 (RISC, 133MHz) from Hitachi is used as the CPU.
The program of the CPU is stored in the flash memory. This program can easily be upgraded
on site through the interface.
During upgrading, the program is downloaded to the PRAM by the CPU and then stored in
the flash memory of the CPU.
When the receive data is read from the interface, the CPU loads the data in the picture memory
through the PDC-CTR. The picture memory consists of a 128 MB DSRAM.
The PDC-CTR performs necessary mask processing, performs X-Y conversion, then transfers
it to the HDC-CTR PCB with 8-bit width.
Upon reception of data transmission, the HDC-CRT generates the COM signal for driving
Head to Head 3, creates nozzle data, then transfers data to the Slider PCB through the HDCFPC
cable.
It is provided with an absorption fan and cutter drive circuit, Paper width sensor, temperature
sensor, Ink cartridge 1-3 presence/absence sensor, Ink cartridge 1-3 end sensor, Ink cartridge
1-3 read circuit.
