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 6 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.
This feature effects the service life of the ink pads. The ink pads reach their capacity earlier by running this feature. If the ink pads have reached the end of their service life, contact Epson Support to request replacement.
When the ink levels are insufficient for Power Cleaning, you cannot run this feature. Even in this case, the levels for printing may remain.
