2.2.5 Pump Mechanism
The paper feed motor drives the pump mechanism when the transmission gear is moved to the
position where the paper feed motor engages the pump mechanism gear trains, when the carriage
unit is at the ink system home position. The figure below shows a block diagram of the pump
mechanism. Pump system operation depends on the rotational direction of the paper feed drive
motor, as shown in Table 2-6.
