2.1 OVERVIEW
Since the printer mechanism of the EPSON Stylus COLOR 200 is the same as for the EPSON Stylus COLOR
IIs,this section only describes the differences inelectrical circuitry.
2.1.1 C199MAIN BOARD
The main control board for the EPSON Stylus COLOR 200 is the C199 MAIN board. The major
difference betweenthe electricalcircuitry ofthe C199MAIN boardand C160 MAINboard (usedin the
EPSON Stylus COLOR IIs) is that the new board incorporates a new CR drive circuit. The figure
below showsa block diagram of the C199MAIN board circuitry.
