Automatic Refill System for HP Black Ink Cartridges

Easy to use. Learning curve is no problem, take your time the first time, no problem. The next refills will be brain-dead. Re-fills for under 4 bucks. Also, I "heard online" that you can buy bulk ink (ebay carries) and refill your refill system, so you can even get your next refills less expensively. At some point you do have to buy an OEM cartridge as they are not infinitely refillable.

Got this to refill a black cartridge and it worked perfectly to start but the ink wouldn't go INTO the cartridge, which had been empty for a while. The instructions say not to let the cartridge dry out. So I guess mine did and thus the refill almost worked. But it is easy and no mess. So I'll keep use it on the next cartridge when empty (right away this time). I would still recommend this refill kit.

It's not listed on the description, but this also works for hp 74(xl) cartridges.
The reviews which say how easy this is to use are pretty on target. i just want to describe how to use it for those debating to buy this, I didn't see this info when i was thinking of purchasing.

the top half contains the black ink- 84ml of black ink. a long needle is attached to the top. You place a plastic guide on top of your cartridge. and then you hook your cartridge on the gray holder.
You flip the ink container upside down and place the gray piece (with your cartridge attached) inside. the needle will go thru the exposed hole and pierce the foam inside. Then you flip the container and wait for the ink to fill your cartridge. The directions say to watch for when the air bubbles stop. and the ink tank is marked so you can watch for level change.

If your cartridge's foam is dried out (taking the cartridge out of the printer too long, or waiting too long to refill) the ink won't penetrate. But next time you'll know better to make sure you refill as soon as you notice the ink getting low on your cartridge. this will help extend the life of your cartridge. usually you can get 4-5 cycles on your cartridges. My cartridge was too dried out (dead) but this refill system will work great on my next cartridge.

the 3rd party seller- Shoplet was great, Amazon-level reliability. they send emails when they're shipping. I received mine the next day!

Worked perfectly from the start. Simple. Clean. No hassle. Pay close attention to instructions regarding using pump to stimulate ink flow, and avoid refilling a cartridge which has been empty for some time (it has dried up and may not refill properly). Also, as another reviewer mentioned, the calibration marks on the ink tank serve as an excellent guide to monitor how much ink has gone into the cartridge.

Construction quality is very precise... much better than I would have expected for a product of this nature. This product will save HUGE dollars over feeding HP their profit gouging prices for OEM. Hooray!

The shipping was faster than I expected. GEAT shipper. At first I thought that this would be complicated and won't live up to expectation from the reviews that I read. Well it was easy once I read the instructions. There was no mess and I din't get a drop of ink on the sink or on my hand. I highly recommend this ink refill kit. Just follow the instructions. I'll be returning to purchase more.
