Cleaning the Print Heads
The print head Cleaning and Deep Cleaning functions allow 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.
Cleaning
1. Select Utilities from Remote UI
2. Click Cleaning
Before performing Cleaning, check the following items:
Check whether the printer is on and open the printer's cover.
Check the following items for each ink. Then, if necessary, perform
Cleaning .
• Is there ink remaining?
• Did you push in the ink completely until you heard a clicking sound?
• If the orange tape is there, has it been peeled off completely?
Any remaining tape will hinder ink output.
• Did you install the inks in their correct positions?
3. Perform Cleaning
Click Yes .
Print head Cleaning starts.
4. Complete Cleaning
Next, the message for Nozzle Check pattern printing is displayed.
5. Check the results
To check whether the print quality has improved, click Yes . To cancel the check process, click No .
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.
