Cleaning the Print Heads
The print head Cleaning function allows you to clear up clogged print head nozzles. Perform print head
Cleaning if printing results are not satisfactory or if a specific color fails to print, even though there is enough
ink.

2. Click Cleaning
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. Perform Cleaning
Check that the printer is on and then click Start .
Print Head Cleaning starts.
4. Complete Cleaning
Click OK when the confirmation message is displayed.
The Nozzle Check dialog box will open.
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. 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.
