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.
BACK TENSION 0.97x10 -3 - 1.71x10-3 N�m (10-17gf·cm) PLAY TORQUE 1.47x10-3 - 2.45x10-3 N·m (15-25gf·cm)
NOTE: To prevent the tape from damage, turn the guide rollers slowly. (7) By operating the tracking button (both in + and - directions) in the manual tracking mode, vary the output level of the FM waveform from maximum to minimum and vice versa to confirm that the waveform varies nearly in a flat shape. (8) When the FM waveform breaks in the level varying process, subtly adjust the height of guide rollers at every breaking point so that the waveform varies as flat as possible. Repeat the above steps 6. and 7. several times to confirm that the waveform is flat as a whole. (9) Playback the SP stairstep signal of alighment tape and adjust the tracking control to maximize the FM waveform, confirm that FM waveform variation is always flat. (10) Record the signal and play it back in both of the SP and EP modes, and confirm that the FM waveform is flat in both modes. NOTE: Among the above-mentioned adjustment steps, the items of No.9 and No.10 are needed for the EP model only.

Fig.3-3-6 (11) Through the above steps, confirm that there occur no wrinkling and damage in the tape around the PINCH ROLLER and TU GUIDE POLE whenever the deck is in operation of Loading/Unloading, Search Rewind and at mode change from Search Rewind to play mode. If wrinkling or damage in the tape occurs around the TU GUIDE POLE, adjust the angle (slant) of the A/C HEAD to the tape. So that the tape normally runs along the lower flange of the GUIDE POLE.

Fig.3-3-4 Remove the Cover (JIG) shown on Fig.3-4-1. Connect the JIG CONNECTOR CABLE to CN25 on the MAIN BOARD ASSEMBLY as shown on Fig. 3-2-2. Observe signal at V_TP_FM with external trigger from V_FF on the JIG CONNECTOR CABLE. Playback the SP stairstep signal of the alignment tape and maximize the FM waveform by the tracking button. Set the tracking control to the center position by simultaneously pressing the tracking (-) and (+) buttons and maximize the FM waveform by the tracking button. If the observed FM waveform is not flat, adjust the height of the SUPPLY of TAKE-UP GUIDE ROLLER with the roller driver.
