Non-HP ink cartridges

[LawnieJoe]

Hi, we just bought an ISY brand (non-HP) ink cartridge for our HP 6950 inkjet. The printer is refusing to print with a non-HP cartridge installed. I cannot believe that it's legal for you to do this, and I'm assuming this is a mistake.

How do I disable this function and continue using non-HP ink cartridges?  And please don't give me some tired excuse about protecting me from poor print quality or printer damage - I'll take my chances, thanks.

Thanks, the firmware seemed to be up to date already, but I'll try that again and see if it changes anything.

Appreciate the response.

Hmm, it appears that the firmware updates are potentially causing the problem, not solving it.

Thanks for the response again - if you could forward a request, I'd greatly appreciate it!

Hello LawnieJoe,

I have owned an HP LazerJet 200 colorMFP M276nw printer for a few years. I am satisfied with the print quality of the product even though I have always used Moustache compatible replacement cartridges.

Recently, I had to replace the cyan color cartridge. I used a compatible cartridge as usual and to my surprise, the printer tells me that the level is very low and it only prints black. However, the other three cartridges are also compatible models of the Moustache brand and the remaining toner content is indicated in %.

I searched the internet for a solution and came across the following article.

Reading this article made me furious, I felt like throwing the printer out the window. It is certain that if the company persists in this way and does not withdraw the obligation to use the original Toner cartridges, it will be the last HP printer that I will acquire and I am ready to bet that many other customers will do the same. Good luck to HP in recovering this lost customer base.

So I have an HP 6970 (the computer and other electronic info tells me it is, but the label on the front of the printer says 6978). Same issue and I've had the problem with my last cartridge's. At some point it just started working - not sure if I did something but it is happening again. I just want to say to HP - how dare you? You did not advise me that I would be obliged to purchase your overpriced products in perpetuity. You have halted my product from working. Once again I am spending valuable time trying to get the issue fixed with a download but to no avail. Tomorrow I will purchase a new non HP printer, and never buy another HP product again. You have my information if you wish to reach out to me.
