NCU Cleaning

The NCU uses a sensor to monitor the ink droplets
ejected from the print head nozzles. Continuing to use the
dirty NCU may prevent the nozzle check function from
operating correctly.
• Be careful to avoid leaving fragments from the
cleaning stick behind when cleaning. These
fragments will increase the risk of ejection fail-
ures (e.g., nozzle clogging or deflection).
