Refill HP cartridges
In the cartridges of this company, the print head is aligned with the reservoir. This is a big advantage, because in case of unsuccessful refilling, the cartridge is simply thrown out and a new one is bought and the printer will not be damaged. HP color and black cartridges are different in design.
The first ones, like the Epson models, have a reservoir with a sponge, and they seem to refuel. First, glue all the holes except those located on the top cover. It is through them that we inject the syringe needle and slowly (when refilling practically any ink cartridges, ink needs to be entered slowly) we pump ink. Then you need to wait a while until the ink dissolves on the sponge.
The color cartridge refill process for the HP DeskJet 400/500/600 is a bit more complicated. First you need to remove the top cover (this is not as easy as it seems at first glance). Under it there are 3 holes for various colors. We glue two of them, and in the third we inject new paint with a syringe. Then we glue the other two, and so on. In the end, remove the entire tape and return the top cover to its place. You can fix it with the same adhesive tape.
Now let’s deal with black cartridges. On HP DeskJet 400/500/600 models, pressure inside the tank is generated by special air bags. Keep this in mind, because after damaging such a bag, all ink will leak out and the cartridge will have to be discarded. In older models, the difference between external and internal pressure is used, and therefore, such a problem cannot arise.
For younger models, the refueling process is as follows. First, tape all the ventilation holes on the bottom and the cover of the cartridge. Then we drill a hole in the corner of the cartridge (by the way – on some models there may already be a finished hole; in this case, you only need to push a special ball inside to cover it). Next, we use the syringe to pump ink. After that, glue the hole tightly with tape (or, if you use a special kit, plug it with a stopper). It is here that the greatest number of errors are made. The hole must be closed very tightly. Otherwise, the cartridge will leak, and often this happens when it is already inserted into the printer. Believe me, this is very unpleasant.
That’s all. We unstick the tape from the ventilation holes. Now it remains only to pump a little air into the upper technological hole. Try not to get dirty, as ink will drip from the nozzles of the head. Air injection should be stopped when ink stops flowing from the overpressure relief port located at the bottom of the cartridge (usually 2-3 cubes are enough). By the way, for some cartridges (for example, for the HP 51645A), you do not need to pump air, but rather pump it out. For this, there is a special suction cup in the filling sets. We take this simple device, click on it, put it on the nozzles of the print head and weaken the pressure. As a result, excess air is pumped out of the cartridge. It is necessary to pump out before the appearance of ink from nozzles.
It is much easier to refuel using a special cartridge holder. In this case, you will no longer need to seal the ventilation holes – they will be closed by the holder (everything except the top). Just drill a hole for refilling, then fill the cartridge, and then pump a little air into the upper ventilation hole and seal the filling hole. All – you can take out the finished cartridge.
With black cartridges of the older models, everything is much simpler. It is enough to separate the film covering the special hole near the nozzles and push the cork ball inside. Then fill in the ink and seal the hole tightly with tape. Now it remains only to turn the cartridge over and wait until excess ink flows out.
Refill Epson ink cartridges
Epson replacement cartridges are just a tank full of ink. The head and printing mechanism are in the printer and cannot be replaced. More precisely, they are liable if they fail, but this will require spending up to 75% of the cost of a new printer. And what’s most interesting, the Epson print unit “flies” most often because of the use of fake cartridges or bad ink in the home, and the guarantee is not valid in case of such breakdowns. So if you are the owner of an Epson printer, it is better to think ten times before deciding to refill! However, the process itself is very simple.
The most important thing is not to remove the cartridge from the printer for more than a minute: otherwise the print head will dry out and you will have to suffer with cleaning it. And this, believe me, will not lead to anything good. The way out of this situation is quite simple and … not very pleasant: you have to purchase another cartridge — empty it, put it in full immediately.
The filling procedure itself, as I said, is extremely simple, and it is the same for color and black models.
