6.7.2 INK SUPPLY AND KNEADING MECHANISM
Ink Cartridge Installation
The ink cartridge [A] is in the drum. The ink cartridge set sensor [B] (a push switch)
detects the presence of the ink cartridge.
Ink Supply Mechanism
The ink supply mechanism is completely inside the drum. The ink pump motor [C]
drives the ink pump [D], supplying ink from the ink cartridge to the ink roller [E] via
the ink distributor [F].
Ink Pump Operation Monitoring
The ink pump sensor [G] monitors the number of rotations that the ink pump makes.
The feeler on the shaft turns the sensor on at each complete turn of the shaft.
SP1-20-3 can be used to check the number of ink pump revolutions.
