Pump Mechanism
The paper feed motor drives the pump mechanism when the transmission gear moves to where the
motor engages the pump mechanism gear trains (when the carriage unit is at the ink system home
position). Release cam set engages (Figure 2-11) and disengages (Figure 2-13) the pump mechanism
to switch to paper feed (Figure 2-14). Figure 2-12 shows a block diagram. Pump system operation
depends on the rotational direction of the paper feed motor, as shown in Table 2-6.
