epson printer WP-4020 ink leak problem - disassembly

I show how to disassemble the WP-4020 printer to examine the source of the leaking yellow (or other color) ink. This may or may not be fixable but I doubt it. May also apply to the WP-4511 WP-4515 WP-4521 WP-4525 WP-4530 WP-4531 WP-4540 WP-4545. Thank you for LIKING my video.
