3.1.1 Electronic Architecture
The electronic hardware of this printer is based on 1 µprocessors (V55PI NEC).
The electronics architecture of the printer is as illustrated on next figure 3.2.
The controller unit of LA400 printer is implemented on one board.
This board can be splitted in two sections at functional level:
•
The first section is a digital one, mainly dedicated to provide the physical and logical
interface between the host and the engine mechanical/electrical feature.
•
The second one is an analogic one, mainly dedicated to drives the motors, the print head
needles, the generation of the Reset (power-on phase) and Prefault (power-off phase)
signals.
On this board are also provided the hardware dedicated to the Operator Panel management
and to support mechanical options.
The operator panel hardware, is realized on a specific board connected by flat cable.
