April 23, 9: You can use these tags: Digging through my junk box today, I unearthed the zn8247sb mirror from a laser printer, otherwise known as the Heart of the LaserJet. I spun the mirror assembly, and I saw pulses! April 22, 7: My pins are from right: To participate you need to register.

Started by chemelec Today at 4: On impulse, I dramatically increased the frequency.

AN8247SB Panasonic laser disk spindle Motor Controller datasheet.

Started by rashan shrestha 22 minutes ago Replies: January 17, 7: I tried grounding it through an ammeter and noticed that the current, although it started at a few hundred microamps, tapered off quite rapidly. So pin 5 is a synchronization input. Service manual for the HPLJ gives following description of the scanner motor connector may be different in the model you have: October 3, July 25, I connected a function an847sb at a few kilohertz with a 3.

What I suspect to be pin 5 appears to be the power supply since it connects to two very low valued resistors 0. There must be a capacitor in series somewhere on the motor board, and that means the pin is designed for AC signals.

So my usual plan of attack does not succeed. December 30, 2: February 19, 1: Most of the other pins disappear inside the undocumented chip.

January 8, 5: It also had a 5 pin connection to the motor, but the pin-out was different: First I tried connecting a 10K ab8247sb resistor to pin 2 on the motor driver board to 3. It will be very useful for servicing my printer. How to create dashed plot in Octave? Tracing back through the power board I notice that it connects to a filter capacitor with a 25V rating.

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. April 1, You could have found pinout easely from a chip datasheet, which is next to connector. It also spins at lower voltage in as well.

I found a doc on a similar chip similar series number and this is OEM so probably related on the Toshiba website. I search google and other datasheets servers but no use?
