Figure 2-13. Cleaning Mechanism Components
Pump assembly (head cleaner)
When the head is in the capped position (valve closed), the pump motor
creates a vacuum that sucks ink from the nozzles. This is used for
removing ink from the nozzles and nozzle plate, initial ink charge, as well
as cleaning. The waste ink flows through two small tubes to the waste ink
pads.

Head cleaner
The head cleaner has felt on one side and rubber on the other, and is used
to wipe or rub off ink and foreign materials from the nozzle surface.

Pump motor
Clockwise rotation = pump assembly drive for cleaning and so on
Counter clockwise rotation = platen gap adjustment
Cap assembly (one pad for each printhead)
When not printing, the printheads (should) rest on the cap assembly to
make sure the nozzles don’t clog. Also, the printheads are in the capped
position during ink charging, cleaning, and so on.
make sure the nozzles don’t clog. Also, the printheads are in the capped
position during ink charging, cleaning, and so on.
Flushing box
Flushing (dummy printing) is performed over the flushing box, and the
flushed ink flows through the large diameter tube to the waste ink pads.
Flushing fires a little ink to remove ink that may be drying on the nozzle
surface; performed in between print jobs and sometimes during long
print jobs.

Waste ink pads
The waste ink pads absorb ejected ink through the pump assembly ink

When the pads near full, the LCD displays Maintenance Call 0100. When
the pads are completely full, the LCD displays Service Call 00000100. The
pads must be replaced at this time.
