Epson WP4530 Printer (Dewey/PCC)

Epson Workforce - WP4530 Approx 10 yrs old.
Used as a home printer, not for heavy duty office use.
Never had to be serviced, always ran perfect.
Until this past week that is! If you know how to manually clean the print heads (lots of Youtube videos) then that might be all it needs to get this $300 top-of-the-line Epson printer going again.
Also, the service maintenance box will need replacing soon.
Approx $15 online.
Scanner still works fine.
So the problem is this: some of the horizontal text lines were starting to barely show up in a few spots.
So i ran diagnostics, nozzle check, head alignment and head clean.
All these tests only made the problem worse.
I even changed the ink cartridges but nothing changed Have the Manual and startup software disc.
Only the power cord is supplied, no USB or ethernet cables.
No longer have the original box.
Have some expired ink cartridges, both used and still sealed to give away too - They are original OEM Epson 676XL Email only (via Craigslist email relay) - if you send a phone number and ask for a call/text back you will NOT get a reply.
Located in Dewey, the Prescott Country Club neighborhood.
