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.
