Fill-in cartridges for HP 712 - Easier filling than with original cartridges! These HP 712 cartridges are filled through the top fill hole. Simply remove the colored plug and fill with the recommended amount of ink. Then close the fill hole with the previously removed plug. The transparent side plug must be removed during printing. This allows more air to enter the cartridge for used ink, preventing negative pressure from occurring that would impede the ink flow to the print head.

Recommended fill volumes:
Wide, black cartridge 30-35 ml
Narrow cartridges 20-25 ml

Always check the fill level between prints. The transparent casing of the fill-in cartridges allows you to easily check the fill level at any time. This protects your print head from damage caused by "dry" ink. Print.

Please ensure that you use the correct inks in these refill cartridges! Different inks, such as universal inks or inks for other cartridge types, will impair the functionality of your printer to the point where the printhead may be damaged.
