Note: from what I have been reading, some versions of the firmware require modifications to other offsets too. I used and adapted these to reset the drum counter. There are some great resources for resetting almost the same EEPROM on toner cartridges on Samsung printers. It uses a small 4Kbit i2c EEPROM to store the page count.

The above github link has information on how to do that.Īfter some research, it turns out drum unit uses the same technique as toner cartridges to enforce end-of-life. If you have a working printer, you can also sniff the I2C bus to see what data is transferred between the chip and printer.

This github repo has code and information on how these EEPROMs are generally used in printers: It is clearly an I2C device, so you can find it's address using a microcontroller to scan the I2C bus.Ī lot of these EEPROMs work the same way. Research indicates that a lot of these 'toner chips' are nothing more than I2C EEPROMs. Actually this was the reason for this app to reset my toner chip. In combination with the tores arduino scetch it can be used to down and upload dump file from i2c connected EEproms. Schiebevorrichtung und es lief direkt auf Anhieb! todo Nochmal alle Kabel ausgetauscht, Testklammern gekauft statt meiner Ich konnte es letzendlich doch noch zum laufen bekommen. Und natuerlich nicht auf dem EEPROM der Druckerkartusche.īei HP-Tintenspuckern reicht das 'Gedaechtnis' aber nur fuer 2. Mit ein bisschen Pech speichert der Drucker die Seriennummern. Nach erfolgreichem Wiederbefüllen dann immer wieder neu schreiben. Ich würde gerne von einer vollen Druckerkartusche einen Dump ziehen, und Ich finde auch leider zu dem 24C14(L) so gar kein Datasheet Brother Brother HL-元230CDWĪdvices to reset your toner chip with an ArduinoĪrduino sketch to reset your RICOH SP-204 toner chip chip: 24C16L Speer is a python script that can backup, restore and reset the content of the EEPROM of toner cartridges for the Samsung CLP-510 series printers. Using a specific tool that can be bought from a printer accessories store. However, instead of changing the cartridge, many people prefer to refill the existing cartridge.Īfter refilling, you must reset the toner chip so it recognizes the refilled ink level The printer then sends a message to the connected computer, and that's how you know when to change the cartridge. When the printer runs out of toner, the smart chip recognizes the low ink status and sends a warning to the printer. Laser printers use special toner cartridges that have smart chips installed on them. Tools and docs to reset a laser toner cartridge chip
