Theory of Operation

Power control board

The power control board contains the motor drivers and power drivers for the,
motors and fans. It is under the control of the digital motion control ASIC of the
main board. In addition, is functions as a motherboard or interconnect for the
power supply, main board, printhead, network card and I/O boards.

The power control board drives the following components:

■

Process motor

■

Drum (Y-axis) motor

■

X-axis motor

■

Cap/wipe/purge motor

■

Media width motor

■

Vacuum pump

■

Rear fan

■

Drum fan
