To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The color cartridge worked great in my HP printer. Despite all my efforts and cleaning and retries, the black XL cart never printed a thing. I had to go get an HP cartridge (eek!) at a local store to meet a deadline.
I'd thought the vendor would just send me a replacement black cartridge; I'm sure it was a "one off" situation that doesn't happen often. I sent a message through Amazon a while back, but haven't heard anything- must be poor communication.
If they had both worked, by the quality I'd rate them top shelf- but until then, I can't. I'll update if the vendor reaches out.
I am revising my review. I got my ink and it worked great the first probably 10 pages. Now, it work print anything with black ink on a colored print. The only way to contact anyone is to set up service. You should back you product without having to sign up for anything. I have included a picture that should also have black words filling in all of blank lines.
Installed properly, printed good once, after that the color cartridge threw an error that the cartridge was not installed properly. After several attempts and reboot of the printer I gave up and went to Staples and purchase the HP print (expensive)... installed the HP cartridges and it has worked perfectly ever since.
It did not work properly and I should be refunded.
I received the Cartridges on November 21, 2020. Installed them the 1st week of January 2021. On January 21, 2021, even though the printer showed just a little ink usage, I noticed that the black ink failed and the colors fainted. I managed to print a couple of B&W docs using dark blue. For the doubt, I decided to reinstall the HP Drivers (HP OfficeJet 3830). After all that, the printer kept showing just a little ink usage - as before - but now it doesn't print at all. The color cartridge down has some ink when pressed to a piece of paper, the B&W down is totally dry.
My HP accepted the ink and it printed fine for awhile. I do not print often but after 2 months it stopped printing mid print. One sheet was fine and then I could print no more. I cleaned the print heads and cartridges as directed. The black stopped working and the color ink was faint.
I would have given this 5 stars but when I finally used the new cartridges the black is not printing! I tried twice & only the color one works & it’s not as bright of a color than HP. Really disappointed especially since now I have to go spend more money for a black cartridge.
