Description
The ink control section in the drum is supplied with ink in the ink pack by driving the ink motor.
Operation
The piston performs suction and release operation by moving up and down.
When the piston moves up, it draws ink from the
ink pack into the pump, and at the same time
pushes ink out of the upper part of the cylinder.
When the piston moves down, the ink below it is
drawn into the upper part of the cylinder.
