Bill Your link to https://www.vintagecomputer.net/fanuc/FanucManuals1788.pdf "Fanuc System 6T-Model B" is very helpful.
The reader fitted to the PPR is a A860-0066-T001. The readers referenced in the manual are close relatives. Importantly, the manual provides significantly more detail on calibration and lubrication that the PPR manual. Specifically: - p 2 Block diagram - p 7 Block diagram - P 11 .. 20 Tape reader preventative maintenance (i.e. oiling) - p 62 .. 63 Tape reader fault finding; esp node 13 -- use black tape - p 81 .. 83 tape reader photo amplifier adjustment, tape pattern specification, observations and objectives (not in PPR manual - although not all applicable ?) - p84 System connection diagram - p 368 .. 369 Tape codes (ISO & EIA) - useful crib - p 384 .. 385 Tape Reader lubricant specifications None of the foregoing has resolved my problem. However, I now know that you have to adjust for tape color p 82 note 2. And, page 81 provides the cookery for a "zig zag" tape [referenced by pages 47 & 48 of the PPR operators manual]. Next step, make loop tapes (black and yellow) and attempt photo-amplifier adjustment.
