• When not using the machine for a long time, print or copy in both black & white and in color, or
perform print head cleaning, about once a month to prevent degradation of the print head.
• Numerous nozzles are installed in the print head for high-precision printing. Just as the uncapped tip
of a ballpoint pen or marker becomes dry and unusable if not used for a long period of time, the print
head nozzles become blocked by dried ink. Periodically printing or cleaning the print head can
prevent this blockage.
