There is a solenoid [G] on the bottom of the toner cartridge holder.
During monochrome printing, a ratchet mechanism [E] linked to the solenoid holds
the gear [F] which is linked to the toner supply paddle shafts of the C [A], M [B] and
Y [C] PCUs preventing these paddle shafts from moving.
During color printing, the ratchet releases the gear, and the paddle shafts in the C,
M, and Y PCUs are allowed to operate. The toner supply paddle shaft [D] in the
black PCU operates during both monochrome and color printing.
