The HP 712 ink cartridge has a chip. When you have finished printing the cartridge, the original chip notifies the printer that the cartridge is empty. While this message can be ignored, doing so will result in the loss of the ink level indicator and, in the worst case, damage to the printhead. Therefore, replace the original chip with this disposable chip. The disposable chip remembers the last ink level when the printer is turned off and must be replaced when the printer indicates that the ink is empty.

With the disposable chip, you have the same print range as the original HP 712 cartridges.

The chips for HP 712, 3ED70A/3ED67A/F6T78AE/3ED69A are replaced with the expired original chip on the cartridge and take over the ink level monitoring of the corresponding cartridge. It can be used once.

These chips are not a product of the printer manufacturer HP. All manufacturer and brand names are used only to indicate compatibility and are the property of their respective owners.
