How to reset the print counter to zero

On the side of the cartridge is a small electronic contact card with 4 contacts.

For those who are interested in transposing on other models, at the back of the contact card point is a EEPROM BR24L01A-W type memory.

The EDPROM can be reprogrammed thanks to an Arduino UNO card, for instance.

Prepare an Arduino UNO card with the following pins:

Pin 1 (SCL) connected to A5

Pin 2 (SDA) connected to A4

Pin 3 (5V) connected to the 5V port on the Arduino card

Pin 4 (GND) connected to GND on the Arduino card.

Download the ICI program file

Start Arduino and open the .ino file

Upload the program to the Arduino Uno board

Launch the serial monitor via the button at the top right

Make contact on the cartridge card. The 4 contacts need to work well at the same time

Follow the instructions to reprogram the memory according to the correct color (Black, Cyan, Magenta, Yellow)
