When not using the printer for
more than 2 weeks
Always set the printer power to on to perform the fill cap operation.
What is fill cap?
To clear clogged nozzles, use the fill cap function. This function fills the caps 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 function also when several cleaning operations could not clear the clogged nozzles.
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 washes them every three 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 malfunction. This will lead to a replacement of the print heads.
If you have to leave the printer turned off for a long time, follow the instructions below.
For a short period
Clean the print head and the ink flow path with the
storage liquid, and leave the printer with storage
liquid filled.
Prepare the storage liquid set (IP7-137).
Clean the print head and the ink flow path with the
cleaning liquid.
Prepare the cleaning liquid set (IP7-136).
After the head wash, Insert ink trays and charge the
ink system.
Perform the daily maintenance.
When leaving the Printer for
more than one month,
contact your service
representative beforehand.
The service call error is
displayed regardless of
whether service cleaning has
been performed or
not. Contact your service
representative.
