							Cleaning the Print Heads from Your ComputerThe print head cleaning function allows you to clear up clogged print head nozzle. Perform print head
cleaning if printing is faint or a specific color fails to print, even though there is enough ink.
The procedure for cleaning the print head is as follows:
 Cleaning
1.
Open the printer driver setup window
2.
Click  Cleaning  on the Maintenance  tab
When the  Print Head Cleaning  dialog box opens, select the ink group for which cleaning is to be
performed.
Click  Initial Check Items  to display the items you need to check before performing cleaning.
3.
Execute cleaning
Make sure that the printer is on and then click  Execute.
Print head cleaning starts.
4.
Complete cleaning
The  Nozzle Check  dialog box opens after the confirmation message.
5.
Check the results
To check whether the print quality has improved, click  Print Check Pattern. To cancel the check
process, click  Cancel.
If cleaning the head once does not resolve the print head problem, clean it once more.
Important
•
Cleaning  consumes a small amount of ink.
Cleaning the print head frequently will rapidly deplete your printer's ink supply. Consequently, perform
cleaning only when necessary.
 Deep Cleaning
Deep Cleaning  is more thorough than cleaning. Perform deep cleaning when two  Cleaning attempts do
not resolve the print head problem.
1.
Open the printer driver setup window
2.
Click  Deep Cleaning  on the Maintenance  tab
