Chips, Printer Messages & Installation
Installing: with the printer on, open the ink access door and wait for the carriage to stop. Remove the empty cartridge, unwrap the new one, pull off any protective tape without touching the copper contacts, and push it into the matching slot until it clicks. Close the door and let the printer finish its startup routine.
Ink level messages: the printer may show a "used" or "non-HP" cartridge notice, or an ink gauge that reads low or "?". Press OK to continue and judge by print quality, not the gauge.
Firmware updates: HP firmware updates have been known to block non-HP chips. Turn off automatic updates in the printer's settings or HP Smart before you install, and see how to keep HP firmware updates from blocking your ink.

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 MICR ink?
MICR ink contains magnetic iron oxide, so the routing number, account number and check number printed in the line at the bottom of a check can be read by bank sorting equipment.
What else do I need to print checks?
Check-printing software that uses the E-13B MICR font, and blank check stock. Print the MICR line with this cartridge and everything else as normal.
Will my bank accept checks printed with it?
MICR ink is made for bank readers, but bank requirements vary. Print a test check and have your bank verify it before printing a full batch.
Can I print regular documents with it?
Yes, it prints like normal black ink. It costs more, so most people keep a standard cartridge for everyday printing.
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.
