Clean the printhead drop detector

The printhead drop detector is a sensor that detects which nozzles on the printheads are not printing,

so that other nozzles can substitute for them. If particles block the sensor (such as fibers, hair or small

pieces of paper), print quality is affected.

When the front panel displays a warning message that the drop detector needs cleaning, you are

recommended to clean it. If you do not clean it immediately, the printer continues working normally, but

the front panel display continues to show the warning.

CAUTION:

Wear gloves to avoid getting ink on your hands.

1.

On the printer's front panel, select the

icon, then select Replace printheads.

2.

Turn off the printer at the front panel.
