Seven circuit boards support the printer's electronics. (Refer to
Figures 1-3 and 1-4). Two boards, called I/O boards, left and right,
support the front panel, solenoids and sensors. The main board
contains the printer's CPU processor, RAM and ROM. The power
supply accepts the AC input voltage and distributes it or converts it
to various other levels of required DC voltages and distributes them.
The power control board distributes power supply voltages to the
other printer boards and drives many printer motors. The front panel
provides a user interface to the printer. The printhead drive board, a
part of the printhead, manages the signals and voltages of the
printhead's printing elements and sensors. The optional Ethernet
interface card and internal hard drive could be considered the eighth
and ninth circuit boards.
