Refilling my HP DeskJet 2620 Cartridge

[Omarado]

It has been a week since I bought my new HP DeskJet 2620 All in one printer and the black ink cartridge already ran out of ink. The company wants me to buy a new cartridge which costs nearly as much as the printer itself. I can't afford to buy a cartridge every week so I have though of refilling the cartridge with ink. I have a friend who has the same printer and he has been refilling his cartridges without problems for about 4 months now.

Both Black and Tri-color cartridges are of the type (123 HP setup XL) I think

So yesterday , I plugged out my cartridge and slowly removed a bit of the HP sticker on the cartridge and put in around 4 or 5 ml of black ink in the middle hole using a syringe.

My friend told me and showed me how it is done and I did as he told me but however, the printer then prints one page then fails to print anymore. when it fails , it either gives me a completely white blank page or just few lines of black ink around , as if it is still empty.

I put in more ink and i see the ink starts flowing out of the cartridge from the bottom of it so I stop it and I try printing again. like before, it prints 1 page completely fine then fails the rest. I am very frustrated by this and I don't know what to do. Does anyone know what could be causing such thing? anyway to resolve this? Thanks in advance.

It does depend on how much you were printing in that week. If large quantities then the ink could possible ran out but sounds like its faulty cartridges. This happens regularly with compatible. Try re-setting ink by holding stop button down 5 seconds

It's sounds like your cartridge has an air lock. There are a couple of ways to solve this problem one is after you VERY SLOWLY refill the cartridge leave it's set in an upright position for at least 24 hours. The NEW ink has not settled to the bottom of the cartridge. By letting it sit this should help get a full supply of ink down to the print head and displace the air out the top. Do not cover the top refill holes until u are actually ready to use the cart. Also make sure when you inject the ink that you are injecting it as close to the bottom of the cartridge as possible, slowly raise the needle out as you are filling. The intent is to force the air out the top of the cartridge and replace it with the new ink. Lastly there are methods u can use by applying a vacuum to the bottom (printhead) of the cart. This will help to provide a solid flow of ink through the printhead. Some people have rigged an old ink cart holder with a tube on the bottom side of the holder after drilling a hole all the way thru the foam pad the cart sits on. Then open up this hole in the foam to a rectangle shape slightly larger than the actual printhead size. From the tube on the bottom u can use a syringe to apply a vacuum to draw a solid flow of ink. Depending on how much ink u draw out u may want to top off the cart by adding more ink, only this time only insert the syringe just enough to place the ink at the top of the sponge. This ink will eventually move downward in the sponge. Hope all this helps. Refilling these carts can sometimes be tricky. I have attached pics of a trial device I once made but never used. I had a friend make me a much better one that worked pretty good. I dont have it any more so I hope these pics will give you an idea of what I am talking about.View attachment 8843

Hello, you said you removed the HP sticker on top of the cartridge, did you replace it, or use tape to cover the top?
If it's not properly done, you could block the air vents that let air into the cart as the ink exits while printing. If the vents are blocked, you might only get a couple of pages and that would be it. The partial vacuum created would hold the ink back.
