Prompt, please, what role executes a situation of a reflecting square concerning a rotor of the motor of the scanner? The next step was to figure out the relationship of input frequency to output speed, so I connected my trusty old Nixie frequency counter to the output of my function generator and my multimeter set to frequency to the tach output.
Its very interesting i was thinking to use of this motors for demo show helicopter project. February 21, 9: I connected ground to pin three, 12v to pin one and I connected pin 4 to ground to pull it low and the motor spun like a charm. Then, it can give out excellent, completely normally printed sheet and is normal to finish work.
I was able to find the other side of the connector and quickly verify that pin 3 is indeed ground. Could you draw schematic please. And make stepper move forward, and back, or just spin one direction, to be able to see a dot moving along the line.
My pins are from right: I have a module with this IC: Base on Excellent stock resources,Our employees server customer from more than 80 countries. Sell Original new Only. You’re our first Russian customer. What I datasheer was pin 5 is actually pin 1, and it is indeed power. I not so well understand in English, only in Russian. If anyone wants the module you can have it FREE except for postage and packing. Most of the other pins disappear inside the dataasheet chip.
I pulled pin 4 low, and the tiny mirror spun up with a whine to about 13, RPM as measured by the tach output! I didn’t get as much as an email, let alone someone interested in buying it.
AN8247SB, AN8248NSB, AN8248SB
Service manual for the HPLJ gives following description of the scanner motor connector may be different in the model you have: I connected a function generator at a few kilohertz with a 3. This must be the tach output. The information you have provided is really good. Normally ,it take days reach your hands.
Pin 3 is obviously ground because it is the only pin connecting to any large ground planes. ANSB and motor and hex reflector rotor from a brother series lazer printer. I have just dismantled my canon lbp There must be a capacitor in series somewhere on the motor board, and that means the pin is designed for AC signals.
January 11, February 19, 1: Any unauthorized reproduction of any content herein is strictly prohibited. So without this pin motor worked. Even finding a data sheet for the motor controller IC seems a hopeless task Photo shown is representation only.
Similarly I opened up a scanner assembly in a Laser Printer and I found there was an8247sn connection coming out of it. There also is a 5-pin connector, but it definitely has a different pinout. The same controller but another layout. All the best, Tomasz Bajraszewski, Poland – Anonymous.
I had a laser head I pulled out of a Sharp I think printer. We also be able order parts from other part of the world in very short time. What I suspect to be pin 5 appears to be the power supply since it connects to two very low valued resistors 0. January 8, 5: That was really great because I was worried that those two pins were I2C control lines which would have made reverse engineering a lot more difficult.

Since no signal came out of the pin, it must be an input. I was busy with datasheets and other tips.
Only the ANSB is the same. Credit C ard 5.
