Thank you very much for this Service Manual, it helped us a lot to repair the M-4318!
...BUT: The parts list is missing and the free parts katalog on web isn't complete, so now we don't know the part numbers of the defect parts :(
We had to build them out of a working machine, and need the numbers to reorder the missing parts now.
Complete original Service Manual in good (scan) quality!

Note: � All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. � All resistors are in � and 1/4 W or less unless otherwise specified. � f : internal component. � : B+ Line. � H : adjustment for repair. � Power voltage is dc 3V and fed with regulated dc power supply from battery terminal. � Voltages and waveforms are dc with respect to ground under nosignal conditions. no mark : LINE � Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. � Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. � Circled numbers refer to waveforms. � Signal path. J : LINE (ANALOG) c : LINE (DIGITAL)
Note: � X : parts extracted from the component side. � a : Through hole. � : Pattern from the side which enables seeing. (The other layers'patterns are not indicated) Caution: Pattern face side: (Side B) Parts face side: (Side A)
