d) Pump
The pump is a tube pump that pressurizes the ink tubes with rotating rollers to produce a negative pressure for sucking inks. Each individual tube is sequentially
pressurized by two rotating rollers to control the rate of ink suction by a wide margin.
The rate of rotation of the rotating pumps is controlled by driving the purge motor or the HP maintenance jet pump motor as the timing at which the rotating pumps
rotate is detected by a pump cam sensor.
