Cleaning the Print Heads from Your Computer
The 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 machine is on and then click Execute .
Print head cleaning starts.
Important
Do not close the paper output tray until the cleaning is complete.
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
When the Deep Cleaning dialog box opens, select the ink group for which deep cleaning is to be
performed.
Click
Initial Check Items to display the items you need to check before performing deep cleaning.
