

During operation of the cartridge, ink accumulates on the nozzle plate along with paper dust

and other substances foreign to the cartridge. If not removed, this buildup can affect nozzle

directionality and lead to nozzle failure.

Periodically during operation of the cartridge, this buildup is removed by dragging a wiper

across the nozzle plate.

 The stepper motor presses down on the lower link of the wiper assembly by means of the

plastic actuator pressed onto the motor's shaft.

 As the lower link is pushed down, the upper linkage is raised.

 The carriage moves over the small rubber blade, attached to the top of the upper linkage,

causing the blade to wipe excess ink and crusting from the nozzle plates.
