HP 923 Standard vs. High-Yield: Which Should You Buy?
| Version | Part numbers | Black yield | Color yield |
|---|---|---|---|
| Standard (923) | 4K0T3LN black; 4K0T0LN cyan, 4K0T1LN magenta, 4K0T2LN yellow; 6C3Y6LN CMYK 4-pack | 500 | 400 |
| EvoMore high yield (923e) | 4K0T7LN black; 4K0T4LN cyan, 4K0T5LN magenta, 4K0T6LN yellow | 1,000 | 800 |
All versions fit the same printers. Higher-yield cartridges cost more up front but less per page, so they make sense if you print regularly.

Chips, Printer Messages & Installation
HP+ warning: if your printer was set up with HP+ (common on newer "e" models), HP locks it to Original HP cartridges for the life of the printer, and no remanufactured or compatible cartridge will work. Check before you order.
Dynamic security: HP firmware can block cartridges that use a non-HP chip. These are remanufactured from genuine HP cartridges and keep the original HP chip rather than a third-party one. If you see a "cartridge problem" or "used cartridge" message, select OK or Continue; if a cartridge isn't recognized, remove it, check that the protective tape is off, 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.
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. Castle Ink sells remanufactured inkjet cartridges and compatible (newly manufactured) toner.

Will this void my printer warranty?
