Troubleshooting – flashing ink droplet light on the printer

Troubleshooting – Printer lights are flashing.

Cause: This almost always means the ink priming process failed or was interrupted. The printer’s print head has no ink in it, so it cannot print.

Error Indication: The most common sign is a flashing ink droplet light on the printer. Your computer might also display an error message like “Service Required.”

How to Fix It (Manual Ink Charge):

You can force the printer to charge the ink using a utility called “Power Ink Flushing.”

  1. Go to your computer’s Control Panel > Devices and Printers.

  2. Right-click on your Epson L121 printer icon and select “Printing Preferences.”

  3. Navigate to the “Maintenance” tab.

  4. Click on the “Power Ink Flushing” button.

  5. A warning will appear, telling you that this process will consume a lot of ink. This is expected. Click “OK” or “Start” to proceed.

  6. The printer will now begin the aggressive cleaning and ink-charging cycle. This will take several minutes. Do not turn off the printer.

  7. Once complete, it’s a good idea to run a “Nozzle Check” (from the same Maintenance tab) to print a test pattern and confirm that all colors are now printing correctly.
