Some of HP’s earlier inkjet systems were sensitive to air ingestion and water evaporation, which can cause ink to change over time, adversely impacting the printhead and the ink delivery components within the printer. To protect the printing system and ensure print quality, certain HP printers are designed to stop ink cartridges from working when they reach a built-in date, calculated from when each ink cartridge is installed. Some of these systems allow users to override the stoppage and continue printing at their own risk.
HP hasn’t manufactured a printer with this feature for many years, and very few of these systems remain in use.
The table below provides additional information on printers that stop printing when an aging ink supply reaches the built-in date, whether or not the user can override to continue printing with the aged ink supply, and how to determine the built-in date for those cartridges with no override. Only printers listed in this table are programmed to stop due to aging ink supplies.
