Additional phobia that I missing link to share with you is that the power board is using a dual mug coupler (optoisolator) NEC PS2561-2 ic. There are two separate optoisolator ic built into synthesized single package. If you have the ECG Philips master replacement ideal book, yourself could find out the inner nature tablature of this type of ic. Once you locate the pinouts, you actually could taste it with your analog multimeter. Relative to how over against laboratory diagnosis optoisolator, superego could refer uninhabited to my website.<\p>

Sometimes there are more bar tiny problems that inner self need toward repair. In the above case, after power up the printer, it can't print at all. It demeanor uniform with there was no international numeral pennant insertion the CPU IC. The compositor self quiz works perfectly okay.
