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.
3. Execute deep cleaning
Make sure that the machine is on and then click Execute.
Click OK when the confirmation message appears.
Print head deep cleaning starts.
4. Complete deep 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.
Important
Deep Cleaning consumes a larger amount of ink than Cleaning.
Cleaning the print head frequently will rapidly deplete your printer's ink supply.
Consequently, perform cleaning only when necessary.
Note
If there is no sign of improvement after Deep Cleaning, switch off the machine, wait
24 hours, and then perform Deep Cleaning again. If there is still no sign of
improvement, see "Ink Is Not Ejected."
