How to Reset the Waste Ink Counter and Clean the Printhead on an Epson ET-4700 EcoTank

Question:
I followed a guide to reset the waste ink counter on my Epson ET-4700 EcoTank, which has extended the life of my printer by another year. I'm looking for a video or guide on how to manually clean the printhead for this printer. Do you have any recommendations?

Answer:

Regarding your Epson ET-4700 and manual printhead cleaning: manually cleaning the printhead is sometimes necessary if your prints show streaks, missing colors, or if the automatic cleaning cycles are insufficient. Here's what you should know:

1. Identifying Printhead Problems:

   • If the printer displays faded lines, missing colors, or uneven printing, the printhead may be clogged.

   • Unlike standard inkjet maintenance, manual cleaning involves carefully handling the printhead to avoid damage.

2. Manual Cleaning Steps:

   • Power off and unplug the printer before removing the printhead.

   • Remove the ink tanks and carefully detach the printhead assembly.

   • Use lint-free cloths and distilled water or a dedicated printhead cleaning solution to gently clean the nozzles. Avoid touching the contacts with bare hands.

   • Allow the printhead to dry completely before reinstalling it.

   • After reinstalling, perform a test print to check for improvement.

3. Precautions:

   • Manual cleaning can be risky if not done correctly; mishandling may cause permanent damage.

   • Do not use harsh chemicals or excessive force.

   • If the printer shows persistent errors like "End of Service Life," it may indicate that other internal components, like the waste ink counter or internal circuits, need professional service.
