Cleaning the Print Heads

The print head cleaning function allows you to unclog clogged nozzles in the print head. 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 heads is as follows:
Cleaning
Open the printer driver setup window
1.
Click Cleaning on the Maintenance tab
2.
The Print Head Cleaning dialog box opens. Follow the instruction shown in the dialog box.
Click Initial Check Items to display the items you need to check before performing Cleaning.
Execute cleaning
3.
Make sure that the machine is on and then click Execute.
Print head cleaning starts.
Complete cleaning
4.
The Nozzle Check dialog box opens after the confirmation message.
Check the results
5.
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.
Deep Cleaning
Deep Cleaning is more thorough than cleaning. Perform deep cleaning when two Cleaning attempts do
not resolve the print head problem.
Open the printer driver setup window
1.
Click Deep Cleaning on the Maintenance tab
2.
The Deep Cleaning dialog box opens. Follow the instruction shown in the dialog box.
