How to do print head deep cleaning
Note: Print head deep cleaning consumes more ink than print head cleaning.
Perform this procedure only when print head cleaning cannot resolve the print problem.
1. Display the MAINTENANCE screen. (See How to display MAINTENANCE above.)
2. Press the <OK> button twice.
3. Use the <down cursor> button to select CLEANING and press the <OK> button.
4. Press the <OK> button again to confirm. Cleaning starts.
Note: Do not do any other operations until cleaning is completed.
5. Print the nozzle check pattern and check the print head status. (See How to print a nozzle check pattern above.)
Note: If the printed result does not improve even after doing print head deep cleaning, turn off the printer. Then, after 24 hours or later, do print head deep cleaning again. After a given time interval, ink could dissolve itself, resulting in ink unclogging.
When the printed result does not improve even after these steps, replacement of ink cartridges may be required.
