HP 301 Ink Cartridge Refilled but Still Shows Lack of Ink - Printing Solutions

I ran out of ink in my hp 301. that is, it was the end because the printed text was already poorly visible so I added ink I did as it should and it still shows the lack of ink if it is poured! What have I to do with it ?! please advise

Hello.
Did the needle go all the way in? It was like that the first time I filled it.

There is no known way to reset this cartridge. Just because you pour it doesn't mean that the printer will detect the right condition.

and why can't you just do anything about it?

so the needle went all the way ;(

What model of printer do you have. I have an HP Deskjet 1050 and it prints fine for me but shows an empty cartridge.

HP 301 cartridges are so that after refilling they do not show the ink level and there is no way around it, but you can print without problems if they are not airy or dried up.

I also have an hp 1050. Recently I just bought the original 301 ink to be able to refill .. it just shows that it is empty but still does not print .. I've had enough of this stupid printer!!!!!!!!!

The nozzles in the cartridge have probably dried up. Remove the cartridge, pour warm water (temp max 50 degrees) into the jar cap to a height of 6-7 mm, and put it in this water, let it soak for several minutes, after removing it, wipe it dry and try to blow hard into the pouring hole, from underneath a drop of ink should appear on the bottom.
If you don't want to play around, some stores refill cartridges for PLN 15-20 or you can buy a high-capacity replacement much cheaper than the original.

I had the same thing when the cartridge was not used for a long time, but I got a liquid to unclog the nozzles together with the regeneration kit. It was necessary to soak the cartridge in this liquid after about 10 minutes. nozzles were removed. The cartridge continues to print.

Hello,
remember that in these models of HP 301 cartridges there are very small sponges and the partitions inside are made so that it is impossible to "pour" more than about 4 ml of ink at a time.

The other side of the coin is that they are weak and do not withstand such exploitation as cartridges for earlier printer models.
Top two regenerations and shows a cartridge error.
Then you have to replace it with a new one.

My cartridge survived 5 regenerations and shows no signs of deterioration. But time will tell how long it will last.

thank you very much for your help !! I don't know how it happened but your method worked may God bless you in your children !

I will add that HP 301 cartridges (300 too) are very sensitive to the type of ink. The ink dedicated to the HP 300 series must be refilled because others clog the head very quickly and there is a problem with printing. I have HP 300 myself, I added Active Jet ink dedicated to HP 56 and the nozzles clogged after a few printed sheets and I couldn't clear them. I had to disassemble the container, pour out this ink and pour another company and it works for now. I also had original HP ink for HP 20 and it also clogs nozzles in HP 300.

Hello, I will join the discussion, I have a problem with ink pouring out of the tanks after topping up. The ink spills out completely, there is no way to print. The effect is that it senses by "weight" that the tanks are full, and nothing is printed. I read somewhere that you need to heat the ink up to 60 degrees before refilling the sponge to "expand" the sponge, but it doesn't do anything, as it was pouring. I even bought a new black original cartridge, after running out I added ink and the same thing. What's up. I bought ink from a good company dedicated to this type of printer. The price of these inks is a bit of a bummer. I was tempted to buy an HP 2050 printer because it was supposed to work despite filling the cartridges because the chips in the tanks are not blocked, but now I regret it. The printer works but does not print and this is the effect. So how are my colleagues with this ink pouring?, maybe some hints what should I do?.

Did you use a clip (refill attachment)?

No, I fill through the hole in the container directly into the sponge. What about this clip?

You use it to pull the ink through the nozzles to create a "vacuum".

The holes in the head are unobstructed even too much because they totally pour

Maybe you added too much ink, a regular 300 type cartridge is divided into two parts, one middle is a sponge into which 4 to 7 ml is poured and the other is empty. If you pour it full into the middle part or pour it into the other empty part, the weight of the ink causes it to flow automatically through the nozzles and that's why it pours. In older types of cartridges, there were special methods of maintaining a vacuum so that the ink would not spill out. Now the capacities of the cartridges are microscopic, so the sponge itself is enough. One more thing is the hole for equalizing the pressure which is under the sticker, it is to be partially exposed in half a square which can be seen in the enlargement.

Well, I just "rip" the old black ink and there are actually two chambers, one with a sponge, the other empty. I don't think they are connected to each other, so how does the ink flow into this chamber without a sponge? I guess because I don't see any connection between them. I read somewhere that you can put a sponge in the empty chamber, would that help?. There is too much ink and the ink drops coming out of the nozzles cannot get through the excess ink and hence these problems. Has anyone out there done any experiments with these tanks? These are tanks from the 301 series. I only have one tank with colors, and how is the issue with the chambers handled there?

In the color cartridges of the 300 series, there are 3 chambers with sponges for colored inks and 3 empty chambers, so you can pour even less ink there than for black ones.
In the black ink container, you can remove the plastic walls (with pliers, soldering iron, drill, etc.), insert a large sponge and there will be an XXL cartridge into which you can pour 20 ml of ink. I cut the walls and put 3 washed and dried sponges from the old colored HP49 cartridge next to each other and it works, but I don't fill the ink completely. You can also buy sponges to size, e.g. in the online store -agawa.pl.
Color is more fun because you would have to cut 3 walls and insert 3 sponges.

BOBBY1234 where did you rip the tank to cut the side walls or the top cover?. In my black cartridge, I noticed that there is a very "narrow" border between printing and ink pouring through the nozzles. When it doesn't print, I add half a ml of ink and pour some text printing - a few pages and then the end of printing again. The entire tank is heavy, so I'm assuming there's ink in it all the time. I have to try these sponges. I also noticed that inside the cartridge there are two small holes between the chamber with the sponge and the empty chamber and I think this is the problem, probably after the sponge tank is overfilled, the ink flows into the empty tank and through the holes it gets to the main channel and overflows under its own weight through the nozzle. I doubt that 20ml of Ink entered the tank because the capacity of the tank itself is about 15ml after cutting out the walls inside.

I cut the lid from above, cut the middle walls with pliers and a soldering iron. I put 2 sponges from the colored hp 49, poured over 10 ml of ink at the beginning into the first one and pressed the second one.
There is a mesh at the bottom of the tank - the filter must touch the sponge with the ink, if there is no direct connection, it will create an air cushion and it will get air.
The dimensions of the container inside are 4.5x2.5x2.5, so theoretically it can contain even more than 20ml.
After pouring the ink and sealing it, it is very important to extract some ink with a suction device or push it out from above by blowing hard if there is no suction device and leave a vent hole after sealing the lid.

Nice, but I think with a dremel I'll try to do the same from the side. I will cut out the side wall and remove the partitions. The top is needed because all these vents are there, but I would like to keep them. After inserting the sponge and gluing the wall, it should be OK. Thanks for the hint. I am also interested in the vent hole, whether you do it on the "OKO" or with some specific parameters, because in the original the air comes through some squiggles.

Under the sticker, these squiggles are venting channels and end with a rectangular cutout in the lid, which is partially under the sticker and partially exposed to allow air access. The regular HP 300 cartridge has one channel exposed and the XXL model has two. I peeled off the sticker and glued it back and exposed the second tubule.

Ok, I understand, will try it next time.

I also had the same problem and managed to solve it. The filled cartridge must be placed in the clip and suck the air out with a syringe from the bottom (I did it 3 times). It started printing fine for me.

I filled the cartridge, sucked the air out until the ink went, I sealed the sticker in advance, I put it in the printer and it shows that the container is empty and does not print or copy. HP Deskjet 2510 printer. It was the original first time refilled after exhaustion of the cartridge. I applied 15 ml of mascara. Why is it showing an error

I had a similar action with the 300 ink and the F2480 printer. I filled the container (using the clip) right after the original ink ran out (a few minutes after - so there was no question of dried nozzles). The cartridge initially did not print. According to the recommendation from the forum, I blew into the hole created after filling until the ink came out of the lower nozzle and from that moment the cartridge prints.

It's not a scam, it's a trick of the uninterested. I had the same with the HP302 ink. I bought a new one (the smaller one) and when I printed these 200 pages, it was gone. I added as always (and before that I had carcasses 27 and 28), because it always worked - in the holes near the vents. Not here. One side printed just fine and that's it. It just turned out that in the 302 you have to pour into the middle hole masked with a black dot on the manufacturer's sticker, but after refueling the needle hole needs to be sealed with an additional sticker, otherwise the ink pours from the bottom (probably some vacuum or something ...). So it would come out that in 302 there are as many as 3 chambers, of which only the middle one with a sponge and access to the head. What about the other chambers? There are probably some connection channels in XXL inks, because in mine - the "boot" one, there is a maximum of 4ml. And in XXL they say 10-12ml.
