To assist your Printer in operating effectively
Turn the Printer off
Always set the Printer power to on to perform the fill cap operation.
Fillcap is...?
- To remove nozzle clogging from nozzle surface, use fillcap option. This option fills the cap with ink to
soak the print head (nozzle surface) in the ink for a minimum of 1 to 2 hours. If possible, leave the Printer
overnight.
Use this option also when nozzles cannot be fixed by cleaning repeatedly.
The Printer has an internal clock which allows it to automatically wash the print heads, flushing some ink through
the print heads, which keeps the print heads in good condition. The Printer automatically washes the print heads
72 hours after the last printing, and then regularly washes every 3 days.
If the Printer is turned off for a long period, this process above does not happen. If the ink does not flow through
the print heads regularly, the ink will dry inside the nozzle, reaching a point where they cannot be recovered and
the print heads will fail. This will mean a print head replacement.
So, if the Printer must be turned off, follow the guide below.

CAUTION
- To protect the print head, do not leave your Printer for more than one month with no ink charged.
- During the service cleaning or head wash, do not open or close the front cover or the lever. Otherwise, the Printer may
restart its initial operation from the beginning, while wasting the ink and cleaning liquid.
