Hp 2175 flashes "remove and check cartridge"

SOURCE: HP PSC 2355 Won't accept refilled ink cartridges

If problem is what I think it is (that is if you cleaned whole thing and it is connected proprely), you have only one option. To buy at least three cartridges...problem is due a small trick made by HP. Printer remembers at least two cartridge serial numbers, and then wont accept refilled ones. But if you first stick one, then the other, and on the end the third one(only this one should be really full) it should reset printer and it should foul it to accept it. But on some printers it needs up to five cartridges! What a waste of money :( Anyway, hope this helps...

Have you purchased a refill kit yet ? If so there are great instructions with them. but generally there is a rubber cap on the top of the cartridge you remove. You draw the ink into a syringe and slowly inject it into the cartridge. Slowly is the key. Replace the plug and tape over it with the tapes they provide. Its important you get the sealing done right or air will enter the top and the ink will flow out of the cartridge into your printer.
It's really not hard at all, just follow the procedures carefully and in 10 minutes you will have the cartridge functioning again.
Just follow the directions, you will be fine.

You will need to reset the Flag gear. This is situated at the other end of the cartridge to the refill hopper. There are 3 screws that you must undo first, you will notice a small white flag gear, this needs to be turned back to the beginning of the curved section. After removing the screws, CAREFULLY remove the end plate and pull the flag gear out slightly and return it to the beginning position, which is the other end of the curved section. Put your cartridge back together again..Your printer will now accept this refilled cartridge

Yes you could refill those types of cartridges, but i would not suggest it! Unoriginal ink will cause loss of quality and also if not sealed correctly it could spill allover the printer and will certainly cause damage.
