To assist your Printer in operating effectively
When you do not use the Printer for 2 weeks or longer
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 has been left turned on and has not been used for 2 weeks or longer, it is necessary to wash the
print heads, charge the ink system, and perform daily maintenance using the procedure below.
If you have to keep the Printer turned off for a long without using it, first perform a service cleaning using the
procedure below, and then turn the Printer off.
For a short period
Clean the print head and the ink flow path with the
storage liquid, and leave the printer with storage
