Epson ET-3850 how to run a Power Cleaning from the control panel
When white or dark lines or missing nozzles remain after cleaning the print head several times.
Steps
Running a Power Cleaning consumes a lot of ink, so you should run it only if necessary. Make sure each ink tank is at least one-third full before running a Power Cleaning, or it may damage the product.

Power Cleaning may cause the maintenance box to reach its capacity sooner. When the maintenance box is full, you need to replace it to continue printing. If the ink levels or the free space in the maintenance box are insufficient for Power Cleaning, you cannot run this feature.
