This is a good quality scan of the Operation & Maintenance (Service) Manual for the PAL version of this high-band broadcast umatic, BVU-800P
All schematics and lineup procedures appear to be included in this one manual AFAICT.
The file size is just over 113 MB which gives an idea of the quality and number of pages.
All of the schematics, which contain some fairly small print, are easily readable when you zoom into the page.

THEORY OF OPERATION
4-5. Detectors
(1) Home Position Detector A photo-interrupter is used in the home position detector, which is set at the left side of the frame unit. ON/OFF signals are generated according to the position of the shield plate mounted at the base of the carriage, and the printing position is determined by these signals. Paper Out Detector Paper out detector is located at the paper insertion slit. When paper is present, the photo transistor with the reflecting type photo sensor goes on. As soon as paper runs out, this transistor goes off, outputting a paper empty signal.
