***118INK Refilling kit***Compatible With HP ENVY 5540 All-in-One Printer INK CARTRIDGE REFILL KIT & TOOLS HP 62 HP 62XL HP62 HP62XL

I have learned that If your cartridge has run dry of ink it is highly unlikely that it will work upon refilling even if only for a short period of a couple of hours; and particularly if one of your colour inks runs dry and you continue using it with the remaining two colours. This has at least been true for my original HP62 cartridges.To have reasonable success it is necessary to refill the cartridges when they have run low and have not dried out. So far, using the black ink I have had partial success. The problem that I experienced after following the instructions was that the printing quality was fine for a couple of days but when the printer had not been used for three or four days afterwards, I started to experience drop out and uneven printing when it was used again. Cleaning the cartridge heads didn't resolve the issue and I was forced to prime the cartridge again using the supplied syringe but the problem only returned again a couple of days later. If you are doing long print runs it is worth the effort but if you only print occasionally it is not practical.My success level with filling an original HP62xl colour cartridge was also very short lived but that was because two of the original inks had long dried out before I refilled the cartridge and it had not been used for three months.After another expensive HP62xl colour cartridge ran out I made a second attempt. I was successful filling the used cartridge twice while printing a large number of colour copies. However, on the third refilling the Cyan chamber of the cartridge stopped flowing and refused to print. Consequently I have temporarily returned to using HP original cartridges.As a consequence of this experience I am sadly unable to recommend this product, even though I wish I could. However, given the exorbitant cost of original cartridges it is still worth trying. I have become disillusioned with the cartridge concept printers because the cartridges are prohibitively expensive and I now intend to move to the Eco-Tank concept printers that run on bottles of ink and are much less expensive to maintain. In the next 10 years perhaps we will see an end to the cartridge concept printer due to the ridiculous cartridge prices and exceedingly poor value for money. I am now saving for a replacement bottle filled ink printer.

It was OK but did have issues with gloves and the purging of cartridge as jig did not appear to make a good seal on the cartridge. If I brought again I would look for a better product.

Extremely good thank you very much. Robert...
