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.
I always have a set of cartridges on hand for my HP 4500 ink jet printer. This last time I decided to try a non-HP product, Greenbox for the HP 61 replacements, from Amazon, since they had good reviews when I bought them on September 9, 2019. Yesterday it was time to replace them, so I grabbed the Greenbox cartridges and, easily, replaced the HP cartridges. The printer didn't recognize either one, so I followed Greenbox's enclose instructions, using the enclosed eraser to 'shine' the contacts on the cartridges. The color one was recognized, but the black one was not. I re-'shined' the black one several times, turning the printer off and back on again, finally resorting to an actual pencil eraser, but to no avail. Ran down to Staples and got the HP replacements and all's well. On top of all of that, Amazon's time to return was October 8, so it clearly makes no sense to plan ahead with off-brand consumables. This is the second time that I have tried this, the first being years ago, with the same result. I figured it was worth a chance to try again with the passage of so much time, but I was wrong. Another irritating waste of money, since it cost me the price of both the duds and the HP cartridges to get my printer operational again. Don't waste your money trying to save it.
For reference: I have an HP InkJet 4630. I use my printer mainly to print documents for school as well as the occasional recipe. IE, not high volume.
I purchased this solely due to price. Typically, I purchase the normal HP black and color package as the XL is far too expensive (~$70 for the black and color pack). This was a much more attractive price point. However, I was warry buying from a third party, especially for something I wasn't sure I could return if it did not work or did not fit my printer. So I checked and double-checked my printer model and the ink cartridge was the correct size before ordering. I received the cartridges today and was immediately relieved to find that the cartridges fit perfectly in my printer. Hooray!
It was tricky to get my printer to actually recognize the cartridges. I didn't just plop them in and start printing. I started with the black cartridge because that one was really the one that needed replacing. Closing the door to the printer, an error message immediately appeared. "Could not recognize..." "Please replaced ink cartridge..." My thrifty heart sank. So I took out the cartridge; maybe it wasn't seated properly? No dice. Hm. Maybe it needs both black and color cartridges to be the same? I replaced both. My printer was still angry. I started to get really fussed because I was pretty sure I couldn't return them if they were already opened and the little tab was pulled. So...I turned to my last resort and read the little manual I had promptly discarded after opening the box.
This is what worked for me: That little blue eraser thing they put in the package...IT HAS A PURPOSE. Duh, right? I didn't think that would do anything but I didn't want to throw away $25 without trying. So I did a little erasing of the sensor (be sure to look at the little diagram and erase ONLY the sensor and not the whole strip thing) and popped the cartridges back into the printer. It took about FOUR tries of taking out the cartridges and erasing the sensors when FINALLY my printer was happy. I was diligent because, as I said, I didn't want to throw money away.
I cannot speak to the print quality as I haven't printed much yet. However, the test page that did print came out clear and was free of any spotting or streaks.
For the price, I thought I'd try these At first I thought, Hey! This ink is working great. Other than a chemical smell right after printing, and a very slight color variance in hue, everything seemed fine.
But then .... shortly before the ink levels appeared to be about 55-60%, I started noticing that colors were becoming over-saturated and a warmer hue than they were supposed to be. Next came streaky horizontal lines within colored areas. I re-calibrated my printer, but that didn't help. Then I lost all yellow color, even though I still had plenty of ink left. Next came random tiny ink spots scattered on the page. I thought perhaps my printer's getting old or not working. Tried some HP diagnostics, no improvements.
Today I bought the real HP 61 cartridges, installed them, and it's now printing perfectly. So for now, I'll pay an arm and a leg for the real HP ink. Lesson learned.
