d) Pump

The pump is a tube pump type that applies the pressure of turning rollers to the ink

tube to create negative pressure for sucking ink. Applying the pressure of two

turning rollers alternately allows greater control over the amount of ink to be

sucked, and helps to reduce the size of the pump unit. With two similar pumps set

to turn in opposite directions, changing the rotational direction of the drive gear

allows the individual BJ cartridges installed in the carriage to be cleaned separately.

The amount of roller turning and the timing of turning are detected and controlled

by the pump sensor.

e) Maintenance jet splash guard

The maintenance jet splash guard receives the maintenance jet ink (test discharge to

maintain the nozzle) directly into the waste ink absorber through the hole by the

side of the platen.
