Don't mix these up: HP 728 comes in more than one size, and every size of the same color fits the same slot. HP 728 is not the same as HP 711 (DesignJet T120/T520) or HP 712 (DesignJet T210/T630/T650).

Chips, Printer Messages & Installation
Installing: open the ink cartridge cover, lift out the empty cartridge and gently shake the new one before pushing it into the matching color slot until it seats. Close the cover and wait for the printer to finish checking the ink.
Non-HP supply messages: DesignJet printers display a notice when a refilled or non-HP cartridge is installed. Confirm the message on the front panel to keep printing. If a cartridge is not detected, reseat it and check the chip contacts are clean.
Printheads are separate: DesignJet printheads are replaced on their own schedule, not with each ink cartridge. If a color is missing after a new cartridge, run the printhead 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
What is in this pack?
One each of matte black (F9J68A, 300 ml), cyan (F9K17A, 300 ml), magenta (F9K16A, 300 ml) and yellow (F9K15A, 300 ml).
Do the 130 ml and 300 ml HP 728 cartridges fit the same slot?
Yes. The 300 ml version simply lasts longer and costs less per milliliter.
Does it include a printhead?
No. The T730 and T830 use the separate HP 729 printhead (F9J81A), which is replaced on its own schedule.
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.
