Epson ET-3850 how to run a nozzle check from the control panel
When printouts are light or banded, to see whether the print head nozzles are clogged before cleaning.
Steps
- Make sure there are no errors on the LCD screen and the output tray is extended.
- Load a few sheets of plain paper in the product.
- Press the home button, if necessary.
- Select Maintenance > Print Head Nozzle Check, then select Print.
- Look for gaps in the printed lines.
- If there are no gaps, select O.
- If there are gaps or the pattern is faint, select X and follow the instructions on the screen to clean the print head.
- If almost the entire pattern is missing, select O and run a Power Cleaning. See Run a Power Cleaning from the control panel.
If cleaning up to 3 times brings no improvement, turn the product off and wait at least 12 hours. Then run a nozzle check and clean the print head again. If quality still does not improve, run a Power Cleaning.
