When a color development unit is installed in the copier, the color switch [A]
is activated by screw [B] at the rear side of the development unit. The color
switch has two microswitches (SW6-1 [C] and 6-2 [D]) inside. The CPU
receives a LOW signal from the microswitch activated by the screw and
determines which color unit has been installed.
