Ink is supplied from the ink cartridge [A] to the ink roller [B] by a pump [C].
The ink pump is driven by the ink supply motor (DC motor) [D] through
gears. There is a pin on the pump drive gear [E] which is coupled with the
pin holder [F] on the pump piston shaft. This mechanism converts the gear
rotating motion into the piston vertical alternating motion.
Two holes on the drum shaft [G] drop ink on to the ink roller [H].
