3.3.1.2
Driver Section
This part is mainly claimed of the PPU 96 ASIC 47537.
This highly integrated circuit serves both to activate further actuators as well as to
recognise and pick up sensors or status signals. This means that this IC sonsists
mainly of registers, latches and selective logic.
Also the motor drivers and the needle drivers are controlled by PPU 96.
3.3.1.3
Needle Driver
The needle driver signals (NOxx) are connected to the printhead via plug X14/X2 of
the connection board to the printhead adapter board. The following diagrams will
show the voltage/current relation, the flow of the current in several conditions and the
principle of driver circuit.
