to drive the servo system mechanism.
4.3.4 Servo Card
The Servo Card or sometimes Servo Driver Board serves as the movement control board
and ink control board packed into one circuit board.
Power to the corresponding ink pumps are sent by this PCB as well as the control signals
from the secondary ink tank level sensors are being received and processed. This binary
information about the status are being processed accordingly in order to provide the power to turn
on the ink pumps to fill in the secondary ink tanks.
The control for the automatic carriage height adjustment is also handled by this PCB as well
as the UV status and the carriage limit sensors. The controls for the ink prime and printhead
