;
very helpful, I could not have cleaned motherboard and replaced the main fan without it
;
Good manual, schematics nice and clear with good quality scanning. Woul dhave been nice to have immediate access after purchasing though.
;
I was very glad recieving the service manal from You. Manuals were delivered promptly and were correct as advertised. A complete and very usefull service manual with all details. Thank you!
;
Very clear copy. No pages missing. Big bonus is that it includes supplement. Price is affordable compared to what others ask for.
;
Found the quality of the copy excellent and a very quick service. I would certainly recommend the service.

Staple motor (FFSM) drive circuit
Staple motor (FFSM)
This circuit controls rotation/stop and the rotating direction of the staple motor (FFSM), and is composed of the CPU (IC10) and the FET (Q10, 11, 12, 13). The DC motor is controlled with the staple motor (FFSM) drive normal rotation signal, the reverse rotation signal, and the brake signal outputted from the CPU (IC10-5, 8, 9pin). To protect the motor and the mechanism, the current limit circuit is provided, which supplies the motor drive OFF signal when the current flowing through the detection resistors R78 and R79 exceeds 3.8A, restricting the current not to exceed 3.8A. 8) Tray motor (FTLM) drive circuit 9) Fan (FFAN) drive circuit
Tray motor (FTLM)
Fan (FFAN)
This circuit controls the tray motor (FTLM) rotation, stop, and rotating direction, and is composed of the CPU (IC10) and the DC motor driver IC (IC19). The CPU (IC10-69, 70pin) outputs the tray motor (FTLM) drive normal rotation signal, the reverse rotation signal, and the brake signal to control the DC motor. In addition, the current limiting circuit is formed with R129, R130, R131, and R132 for the current flowing through the motor not to exceed 0.65A.
This circuit controls the fan (FFAN) rotation, stop, and rotating direction, and is composed of the CPU (IC10) and the digital transistors (Q14, Q18). The DA converter (IC11-13pin) outputs the fan (FFAN) drive signal to drive the motor. The fan lock signal is inputted through the noise filter of R168 and C130 to the CPU (IC10-20pin) by the open drain output of the fan built-in circuit. The logic of the signal inputted to the CPU is H when locked.
