Cleaning the print head
You should start print head cleaning when your print quality is poor.
There are two methods of print head cleaning:
• Cleaning : Requires about 30 seconds and can improve print quality.
• Flushing : Requires about 60 seconds and corrects severe nozzle
clogging. Because Flushing consumes a lot of ink, execute flushing
only when the print quality does not improve after repeated cleaning.
You can start cleaning or flushing the print head with the printer driver or
the operation panel. For details about starting cleaning or flushing with
the Windows printer driver, refer to the Windows Printer Driver Guide or
Macintosh Printer Driver Guide.
To start cleaning/flushing from the operation panel:
1.
Press and hold down the RESUME button.
To start print head cleaning, hold down the RESUME button until
you hear two beeps then release it. Cleaning requires about 30
seconds.
To start print head flushing, hold down the RESUME button until
you hear three beeps then release it. Flushing requires about 60
seconds.
2.
To check the performance of the print head, print a Nozzle Check
Pattern. (☞56)
