Epson 4000 - CLEANING OF INJECTORS OBSTRUED

Good morning My dear, Very grateful for such excellent ATTENTION, PROFESSIONALISM, Your Steps, are accurate and very helpful. I really thank you for helping us keep our equipment in good condition.

What step should I do? To CLEAN ONLY AN OBSTRUED INJECTOR? That is to say; Instead of CLEANING THE HEAD OF ALL COLORS, AN OPTION, to only CLEAN A SINGLE COLOR THAT IS COVERED, OBSTRUCTED? To do this, do not spend the rest of the color inks.

Can I CLEAR, CLEAN ONLY ONE INJECTOR? Instead of the eight colors simultaneously?

What should be done, when a color is covered?

In my little experience, I do the following:
1.- (INJECTION TEST) and Click the (AUTO) Button.
2.- SSCL (SUPER SONIC CLEAN)
3.- (HEAD CLEANING)
4.- EXECUTE CLEANING IN FUND. But a lot of INK is lost

YOU THE SPECIALISTS THAT YOU RECOMMEND, WHEN ARE THE INJECTORS OBSTRUCTED?

Stay tuned. BLESSINGS
