HP 6122 rejects generic cartridges

[Ken1]

Hi, I have an HP deskjet 6122 printer. I tried using generic color cartridges (#78) in it and they work perfectly until I use about 1/4 of the ink or so and then my printer starts giving an error message that states " Incorrect color cartridge, please install the correct HP color cartridge ". I tried cleaning the contacts, reinstalling the cartridge and resetting the ink level and nothing helps. When I install my old dried out genuine HP 78 cartridge, the error message disappears. When I reinstall the generic cartridge, the error reappears. I contacted the manufacturer of the generic cartridge and they instructed me to return it under warranty to the local retailer where I purchased it for another one; which I did, however the replacement did the same thing after the same amount of use. Anyone have this experience? Is there a cure for this? Or do I have to stick with genuine HP cartridges?

Unless I am mistaken, the generics are genuine refilled HP cartridges. I don't recall the 78 printers having date codes on them.

Sounds to me that the refiller did not refill one the trickiest cartridges to refill properly.

I have the HP 932c which uses (and remembers) the serial number of 78 cartridges.
I used this link for the procedure to circumvent the rejection of a refilled cart.
Perhaps your printer could use it too.

I don't think it is a resetting issue since the chance of getting a repeat number or ID on a remanufactured is nil unless you reman and buy it yourself!

What I have found is that somehow the HP can recognize when there is no ink in the head chamber. I wish Canon can do the same!

So what is happening there is that the remanufacturer is NOT refilling the 78 under a proper vacuum process or has the procedure wrong.
The 78 is a tricky cartridge to refill properly when you are short on proper equipment.

My recommendation is to try another brand.

There's a technique (2/3 down) to turn off the error message in this printer.

It's happened twice to this fellow after it was accepted and printing fine for 1/4 of the level. Looks like it's running into a consistent air pocket that is common on both carts. He's even done the reset which eliminates the possibility of bad contacts since he would have needed 3 good insertion to complete the process.
Bad cartridge refills.
