The color control button positions a small roller attached
to the ribbon guide link. When the button is pushed all the
way in, the small roller is positioned closest to the pivot
point of the ribbon lift control plate. This permits typing
in the black ribbon position. When the button is pulled out
one notch from the black position, the roller is over a slot
in the ribbon lift control plate. This position prevents ribbon
lift when the control plate is moved. It also determines the
stencil position. Pulling the button out as far a~ its stop
will permit brings the roller farthest away from the pivot
point of the control plate. This position gives maximum
ribbon lift and allows typing on the bottom portion of the
ribbon (Figure 41).
