The Power Cleaning feature may improve print quality in the following cases.
When most nozzles are clogged.
When you have performed print head cleaning 3 times and waited for at least 12 hours without printing, and then performed a cleaning and a nozzle check, but the nozzles are still clogged.
Before running this feature, use the nozzle check feature to check if the nozzles are clogged, read the following instructions, and then run Power Cleaning.
The Power Cleaning uses more ink than the print head cleaning.
Select Maintenance on the printer's control panel.
Select Power Cleaning.
Follow the on-screen instructions to run the Power Cleaning feature.
If you cannot run this feature, solve the problems that are displayed on the screen. Next, follow this procedure from step 1 to run this feature again.
When Power Cleaning is finished, a nozzle check is printed automatically so you can check whether any nozzles are still clogged.
If all nozzle check lines are not printed completely, wait for at least 12 hours without printing (we recommend turning off the printer), and then run a nozzle check. If all nozzle check lines are not printed completely, run Cleaning and a nozzle check again. If all nozzle check lines are still not printed completely, contact Epson support.
You can also run power cleaning from the printer driver.
