Chips, Printer Messages & Installation
Installing: open the ink cartridge drawer or door for the color you are replacing, lift out the empty cartridge and gently shake the new one before sliding it into the matching slot until it seats. Close the drawer and wait for the printer to read the cartridge.
Non-HP supply messages: the printer may show a notice that a refilled or non-HP cartridge is installed. Confirm it on the front panel to keep printing. If a cartridge is not detected, reseat it and check that the chip contacts are clean and dry.
Printheads are separate: printheads on these printers are replaced on their own schedule, not with each ink cartridge. If a color drops out after a new cartridge, run the printhead check and cleaning from the front panel.

Remanufactured vs. Compatible vs. Original
Original (OEM) cartridges are new from the printer brand and cost the most. Remanufactured cartridges, like this one, start as genuine original shells (including the original chip) that are cleaned, refilled with high-quality ink and print-tested, so they fit and communicate like the original at a fraction of the price. Compatible cartridges are built new by a third party with their own chip. Castle Ink sells remanufactured inkjet cartridges and compatible (newly manufactured) toner.

Frequently Asked Questions
Do I have to replace all colors at once?
No. Each color is a separate cartridge, so replace only the one the printer reports as empty.
Which printers use HP 789?
The HP DesignJet L25500 latex printer, in 42-in and 60-in widths.
Does it include a printhead?
No. L25500 printheads are replaced separately and last through many ink cartridges.
Will this void my printer warranty?
No. Under the U.S. Magnuson-Moss Warranty Act, a manufacturer can't void your printer warranty just because you used a third-party or remanufactured supply. If a non-original supply directly caused damage, that specific repair might not be covered.
How long can I store it?
Store it sealed, at room temperature and out of direct sunlight, and use it within about 24 months for best results. Once opened, install it promptly.
When will my order ship?
Orders placed by 4 PM ET, Monday through Friday, ship the same business day from Long Island, NY, by USPS (2–5 business days). Expedited 1–2 day delivery is available at checkout, and shipping is free on orders over $50.
