Caution
Do not remove cables when the printer is cleaning its print head.
✒ Note
You can also clean the print head from the printer driver. Select
‘Maintenance’ from the ‘MP-21C series’ group in Windows.
Automatic Periodical Cleaning
This printer carries out Automatic Periodical Cleaning to ensure that the
printer maintains optimum print quality at all times. This setting will use
ink during the cleaning sequences.
If you want to only clean the print head by manually selecting cleaning,
you can turn this setting off through the printer driver. This setting will
save ink but you will need to clean the print head manually when
necessary.
To turn the setting to off, select 'Maintenance' from the MP-21C series
group in Windows.
✒ Note
When you carry out cleaning 3 times within one hour by using the printer
clean button, the third clean will become a 'Power Clean'.
