Remanufactured Ink Cartridge Replacement for HP 40 51640A (2 Black)

These cartridges have been working great so far!! Thank you for offering a quality product!

Didn't work

The shipping box was partially crushed when it arrived, with minimal shock absorbing around cartridges! The first cartridge worked well, but ran out of ink very quickly. This produced about 1% of a real HP40 cartridge. The second cartridge had a loose contact strip and didn't work at all. Possibly damaged in shipping, but probably not. Third cartridge worked, but ran out of ink relatively quickly, but probably 10 times better than #1. Working on last cartridge now. A real HP cartridge would last for months and produce hundreds of large size prints. If I'm lucky, these 4 may produce 50 prints!

Happy with my order

one cartridge did not print consistently, the other one did.

Was so pleased, I ordered them for my brother. He has to have them and found them no where Was so excited that you was able to help him.

I have HP430 and I added the color kit for 450C. These cartridges work great to replace HP-40.

Cartridges print generally with lines that are not crisp; they are fuzzy. At least Printronic is honest that they are selling remanufactured product, unlike AIM who advertises new generic, but ships remanufactured product and charges higher price than should be charged compared to other remanufacturers.
