scanner 6L


Prompt, please, what role executes a situation)of a reflecting square concerning a rotor of the motor of the scanner?

Thanks
English is obviously not your native language. I have no idea what you are trying to ask.

Yes, you are right.
I not so well understand in English, only in Russian. Sorry.
Problem such:
I have non-working printer HP LJ 6L.
I send on the printer 1 page(for example, test page), But the printer gives out 1 or 2 completely of black sheet, then 5-7 sheets with alternating black-and-white strips. Then, it can give out excellent, completely normally printed sheet and is normal to finish work.
In the other case, after 11-17 sheets, it stops and all 3 LED's is on(Service Error).
I press the front panel button and Error and Data LED are ON(Beam Error).
Performance the engine test - the same result.

Can you help?

Thanks

You're our first Russian customer. You need a new scanner assembly for that. We don't have any 6L scanner assemblies in stock.

Whether I can repair his?
To me seems, the IC AN8247SB is faulty, but I can not it check up.
Can you help, where I can find the electronic circuit of this block and all printer?

Hello, I search the AN8247 datasheet or schematic of the block of scanner in HP LJ6L. I found your post here, I know it was long time ago, but have you got this circuit? Or maybe know where I can find it? I need it very much, please for any help.
All the best,

I have a module with this IC: AN8247SB and motor and hex reflector rotor from a brother 2000 series lazer printer. I KNOW this part was working. For interest I thought of powering it up, but I too cannot find a data sheet for the device. If anyone wants the module you can have it FREE except for postage and packing.
I shall throw it out after a few months.

hi,

i also recently got a hold of this module... it seems that it's a stepper motor driver... my module RH7-1279, came out of an HP laserjet 5L printer, has a connector with 5 pins... the middle pin ohms out to be connected to ground or common voltage (+12V) , so i assume that the remaining 4 are the stepper motor coils. the 5 pin connector goes through a whole bunch of caps and resistors, so i can't exactly trace back the signals to he AN8247SB pins... if anyone has any pinouts for this part, and is able to post it here... it would be greatly appreciated. thanks. - unknown
I suggest you throw it away.
I just recently had salvaged one complete module too, and I put it on eBay ($1.99).
I didn't get as much as an email, let alone someone interested in buying it.
Even finding a data sheet for the motor controller IC seems a hopeless task...

AN8247SB is a with hall sensor brushles motor controller. THIS MOTOR IS NOT STEPPER MOTOR!!!!!
this controller ic also works with clock pulse. so you can increase the motor speed.Depends to motor clock pulse. Pulse pin must be 4. if you count from left to right.(Motor must up) 1. i dont know but when i take it out, printer made the motor test anyway. So without this pin motor worked. 2.pin is 5v, 3.pin is GND, 4.pin is clock pulse around between 800hz till 2khz, 5. pin is motor supply and this is 12v. But it can works with 24 v too..
and metal surface of pcb( under of the pcb) must be grounded.

AN8247SB THIS MOTOR IS NOT STEPPER MOTOR controller Its BLDC controller.
For a maximum capable rotation
Connect the Pin 5 to +12V DC, And pin 2 and 3 together to Ground.
