Very good service and quick service, very good quality of service manual!

Great tape deck manual!
I'm very positively surprised, because it is a very long manual, lot of pages, drawings, diagrams, description of how to make the alignment and adjustment procedures.
It is as good as the old "Naka" manuals from the 1970's - if somebody have seen them, they know what I mean by that.
I recommend to buy this very much !

Detailed schematic diagram, manual for professionals
s) Ribbon code sensor/luminance quantity adjustment (CN5-3, 19) Function : This is a transmission type sensor that reads ribbon code and starting mark on the ink ribbon. Pair LED luminance is set to obtain the most suitable luminance quantity. When reading ribbon code every time, the threshold level value for judging L or H is changed to the most suitable value. Level : Ribbon code portion is H, others are L Check method : Make sure the threshold level, ribbon cassette should be inserted, ribbon should be rotated correctly, make sure the sensor output. t) OHP sensor/luminance quantity adjustment (CN5-15, 21) Function : This is a transmission type sensor that detects paper kind after feeding paper. Pair LED luminance is set to obtain the most suitable luminance quantity. When reading ribbon code every time, the threshold level value for judging L or H is changed to the most suitable value. Level : Ordinary paper is H, OHP is L. Check method : Make sure the threshold level, transmit the paper, and make sure sensor the output. u) Head thermistor (CN7-27) Function : This thermistor measures temperature of the thermal head. Level : Approximately 2.5V at the normal temperature (25�C) Check method : Measure the voltage of thermistor. v) Room thermistor (CN4-17) Function : This thermistor measures the temperature at the inside of the unit.
