Will Not Fit

• HP 936 is for the OfficeJet Pro 9110b/9120/9130 printers and does not fit these.
• Regional versions: HP printers are region-coded. The HP 924 is sold for printers outside North America and won't work in a U.S. printer.

Chips, Printer Messages & Installation

Installing: with the printer on, open the ink access door and wait for the carriage to stop. Press the old black cartridge to release it, unwrap the new one, pull off the protective tape without touching the copper contacts, and push it into the black slot until it clicks.

Chip: this cartridge keeps its original HP chip rather than a third-party one, so it is the most dependable choice on printers that receive HP firmware updates, which can block non-HP chips. Because the chip has been used before, the printer may show a "used cartridge" message or an ink gauge that reads low or "?"; select OK or Continue. If the cartridge isn't recognized, remove it, wipe the copper contacts and reinstall.

Still stuck? See our guide to fixing a cartridge that isn't recognized or contact us and we'll make it right.

Quality

Remanufactured: an original HP cartridge, chip included, is cleaned, refilled and tested before it ships, so it fits and communicates like the original at a fraction of the price.
