How ink is filled &refilled in inkjet printer cartridges?

You could buy refill kit for that comes tool to open the head of the cartridge refill it and close, I tried that too messy it was not reliable I will not do it again.

i refill carts all the time. some work and some do not. i purchase ink that is manufactured to the specs of the original. sometimes the consumer does not take the necessary precautions to protect the printhead for refilling, which is why some do not work. once the consumer is educated on how to protect the cartridge and the printhead, then theirs have a better success rate.

at the manufacturing plant, the ink is inserted into the cartridge and then the lid is glued on. some of these cartridges have been bougt back and are being refilled, some are new.

with lexmark cartridges, you pop the top to refill the color and on the black, you just need to enlarge the vent hole to insert a syringe of ink. same on the newer versions of HP. however, on the older versions of HP you have to maintain pressure, by removing any excess air. there are certain tools you can buy to do this.

as far as bugs . . . i have no idea what you mean. sorry.

hope that helps.

You can buy recycled cartridges which work as well as the originals, I refill mine also, I have HP, sometimes one will not work, I get the ink at Walmart as refills for HP and they supply a "stand" and instructions which makes it almost mess free. They recommend not refill originals more than 5 times. I don't know about the "bugs", I know I get as much printing out of these as I did the original new ones.

U can get ur cart refilled in Ulhasnagar nr Mumbai....Even u can get refilled cart @ cheap rates...I use it and they are fine.I didnt got any problem with them.

Sounds like you need a continuous ink system (CIS). Try googling it and you should find some retailers that sell these.

HP doesn't recommend to use riffled carridges. Please visit the below link to know about refill cartridges..
