please help! possible to reset printer toner chip?

i know 6&7 pins are bridged. Look at other side of the interface...... actually make this from your Diagram..... the 4th wire is the 5v from USB or the power supply..

That 4th Wire Does not go in Circuit.
From the Tool You should Have Only 3 Wires. Your friend should be able to figure that out from the Diagram. You Must externally power the eeprom to read and write. Thats why The eeprom stays in Circuit. With the Dish Recievers I would Plug in IRD (this would provide power to EEPROM )then with Pony Prog read the EEPROM to extract the Passwords.

instead of using 4 1K resistors

4k7 is the euro way of saying 4.7k,which is a standard size so there was never any need to try to make a "4k" resistor by putting 4 1k in series.
I always used the parallel interface,which was 2 (100 ohm resistors) and 2(1n914 diodes)
You must know the eeprom chip type,I couldn't tell from the pic.
It may be a custom chip like epson uses,which is actually just a timer.
There was a russian program for the epson chips for quite a few years now.

The Diagram calls for 4k Not 4.7K. Instread I use 2 3.9K. Close enough to do the Job and Works Flawless.

Looks Like that should work.
