I tried to reset the computer/ semiconductors by shorting the 110v grounded male plug/cord. I now have the unit all apart. I am not a certified technician. I'm probably going to call them Monday. I pulled the toner assembly out. I watched several videos on you tube. Mr Taylor and others say this toner unit has to be totally emptied, cleaned, and re-assembled. I have not done that yet. I was just seeing if it's removal would make the light go out. I believe that after I clean the toner 4-roller assembly and replace it back into the machine, I will still have a blinking LED (toner symbol). I still have the flashing LED (toner symbol) . I believe that the computer's memory is not being electrically erased/reset. The RICOH FT 3713 has a total of 4 circuit boards. The AC input cord comes into the left rear of the machine and at it's connector, the white neutral wire changes to an orange wire. The AC household chord Black hot changes to blue inside the machine and splits into a total of 3 blue wires heading toward the machine's switch. No I do not have a schematic yet. The switch is spring loaded to the on position N/O (normally open)-momentary on. Just like the one on my computer. It is a rocker style switch like the ones you find in ambulance and tow trucks. The momentary-ON side of the switch is connected to a 16 AWG red and a thin red wire 24AWG? (I don't know the size) (let me Know). The other side of the machine's switch is the orange neutral mentioned above, a black 16AWG and another thin 24AWG white wire. I don't know how the switch works unless I take it off and "ring it out". I cannot physically trace where these wires disappear into the base of the machine. If I take this machine apart much further, I'll have way to many parts to keep track of. I saw a video on you-tube where a guy was turning the white plastic screw adjustment on VR102 of the green microprocessor board. But I'm not going to turn that screw till I at least study the power distribution to and between all the components and the 4 circuit boards and what each circuit board controls on the machine. Does anyone know where I can get a schematic for the RICOH FT 3713 ?
