Keeping Print Quality High
The key to maintaining optimal print quality is preventing the print head from drying out or becoming
clogged. To ensure print quality, follow these tips.
Note
• On some paper, ink may run if you mark over it with a highlighter or water-based marker, or if water or
sweat comes into contact with printed areas.
Never unplug the printer until it is off
Pressing the ON button to turn off the printer will automatically cap the print head (which is equipped with
nozzles) to prevent it from drying out. However, capping is not performed if you unplug the printer while
the
POWER lamp is lit or flashing. This may cause drying or clogging.
Before unplugging the printer , make sure the POWER lamp is not lit.
Print regularly
Just as felt-tip pens dry up and become unusable (even when capped) if not used over extended periods,
the print head may dry out or become clogged if the printer is not used for some time. Use the printer at
least once a month, if possible.
Allow regular ink mixing
The printer automatically mixes ink periodically to maintain optimal print quality. Regular printing helps
keep the ink in good condition.
If the printer is not used for some time, it will automatically mix the ink before printing.
