The link in post #87 no longer works but the service manual for
Epson Artisan 810/Epson Stylus Photo PX810FW/Epson Stylus Photo TX810FW/Epson Artisan 710/Epson Stylus Photo PX710W/Epson Stylus Photo TX710W
can be downloaded here: https://yadi.sk/i/JNFmFRfPg2hZY
The manuals are not identical, the manual at scribd is 100 pages larger then the manual from the other site which might abbreviated. The difference in size might also be caused by the scribd manual being about more printer models.
