The Service Manual for Sansui AU-9500 was very helpfull, in complete and in good printable condition.
Thanks.

Dear Sir,
Document is original service document of sharp. I had a problem with the door contacts. Fuses where blown. With the manual in a few minuts is was clear what the problem was.
Manual was of great help.
With kind regards,

The scan is clear and well readable with very few weaker spots, usually on black background with white letters, but with enough zoom those spots can be read.
Printout is clear, the manual is complete and has all pages scanned.
I would give 5 stars, except that it is not in color, and the schematic and PCB pages are scanned on multiple pages. The document is locked (except printing) so the pages can not be extracted to compose them together for printing on the large plotter
It is worth the price tag.

let's say first that i do not need to have a credit for my opinion, i am a retired sparkie and i voluteerd to fix an electronic device for a local "Youthgroup",as no diagram was present i checked the "net" and gambled on this site and paying some fee via PayPall, i was gladly surprised that the manual arrived as was stated, GOOD SHOW, and best wishes, John

I had been looking for a Manual for my CS2150 for quite a while -- in fact I had just about given up. I saw this site and decided to download the Manual. When I Received it by Email I was really pleased with what I got, with the result that My Kenwood 'Scope is now 100% repaired and working well. As an AV Serviceman, you need a good 'scope, and thanks to this site, and the Service Manual, I have been able to repair it. The Manual was a copy of the Factory Original and the copy was very clear, especially in the area of the Circuit Schematics, where You really need to be sure of what You are looking at.
DEVELOPMENT AND TONER SUPPLY
June 30, 1998
V52 and V5/ detection
The ID sensor detects the following voltages. · VSG: The ID sensor output when checking the drum surface · VSP: The ID sensor output when checking the ID sensor pattern In this way, the reflectivity of both the drum and the pattern on the drum are checked. The ID sensor pattern is made on the drum with the charge corona and laser diode. VSP/VSG is detected every 50 copies (or at the end of a copy job of more than 50 pages) to update the TD sensor reference voltage (VREF). This interval can be changed using SP2-210. This compensates for any variations in the reflectivity of the pattern on the drum or the reflectivity of the drum surface.
V4-. Update
VREF is updated using VSP/VSG and VT. This is done every 50 copies (or at the end of a copy job of more than 50 pages), and during process control initial setting. See �VREF Update� in the Process Control section for details.
V6 detection
The toner density in the developer is detected once every copy cycle after the trailing edge of the image passes through the development roller.
Image pixel count
For each copy, the CPU adds up the image data value of each pixel and converts the sum to a value between 0 and 255. (The value would be 255 if the page was completely black.)
Gain Determination
GAIN is another factor in the toner supply clutch on time calculation. Its value can be 0, 1, 2, 3, or 4. It is calculated every copy using �VREF � VT�.
Toner Supply Clutch On Time Calculation
The toner supply clutch on time for each copy is decided using the following formula: (GAIN ´ Image pixel count ´ 0.7mg/cm /Toner Supply Rate) + 50ms The toner supply rate can be changed using SP2-209.
Image pixel count control
This mode should only be use as a temporary countermeasure while waiting for replacement parts, such as a TD sensor. This mode controls the toner supply using the same formula for the toner supply clutch on time. However, the GAIN value is fixed at 0.7.
