The Power Cleaning feature may improve print quality in the following cases.
When most nozzles are clogged.
When you have performed a nozzle check and head cleaning 3 times and waited for at least 12 hours without printing, but print quality still did not improve.
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.
Make sure that there is enough ink in the ink tank.
Visually check the ink tank is at least a third full. Low ink levels during Power Cleaning could damage the product.
An interval of 12 hours is required between each Power Cleaning.
Normally, a single Power Cleaning should resolve the print quality issue within 12 hours. Therefore, to avoid unnecessary ink usage, you must wait 12 hours before you try it again.
Maintenance box replacement may be required.
Ink will be deposited to the maintenance box. If it becomes full, you must prepare and install a replacement maintenance box to continue printing.
When the ink levels or the free space in the maintenance box are insufficient for Power Cleaning, you cannot run this feature. Even in this case, the levels and the free space for printing may remain.
Select Maintenance on the home screen.
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.
After running this feature, run the nozzle check to make sure the nozzles are not clogged.
For details on how to run the nozzle check, see the related information link below.
If print quality has not improved after running Power Cleaning, wait for at least 12 hours without printing, and then print the nozzle check pattern again. Run Print Head Cleaning or Power Cleaning again depending on the printed pattern. If quality still does not improve, contact Epson support.
