    It appears HP has removed most of those links. Do you know of any mirrors?

    Here is a link to the official HP Support article with working links: https://support.hp.com/us-en/product/hp-officejet-pro-8620-e-all-in-one-printer-series/5367611/model/5367613/document/c05308850/

    Hi, thanks for pointing out that the links seem to be out of date. It looks as though HP have removed firmware version 1640 which was specifically released to fix this problem. I'd be surprised if the files aren't hosted by someone out there, but I can't find them on any reputable sites and I'm not going to recommend anywhere that I'm not personally familiar with.
    The good news is that the HP article you linked to seems to be saying that version 1733 (assuming you've got the 8620 printer) will do the same job, so I'll be updating our article today with the current links.
    If you've tried the download from that HP page, please let me know how you got on with it - I can try some of them out, but I rely on feedback to get the full picture!

    Yes I installed the firmware listed in the article for my 8620 and my third-party ink cartridges work again. What is even stranger is I had disabled updates since I purchasing the printer, the original firmware was still installed, and my third party cartridges were working fine for months.

    My theory is the firmware I originally had would allow third party cartridges to work for a short period, and then issued the "cartridge missing or damaged" error to give the appearance of low quality third party issues. I hope this new firmware doesn't have a similar count down to when third party cartridges will be disabled. I'd still like to get my hands on a 1640 release just in case.

    Now as far as the old links are concerned, I don't trust them, but it's possible they may have removed the old firmware due to security issues. I never bothered asking them on their forum. I'm making sure to keep this 1733 firmware file in case they also take them down and the printer somehow "accidentally" updates.

    My printer 3632 updated inself and installed illegal DRM timebom firmware 1750B.

    My refilled cartridge was working until on April 2, 2018 it started to show cartridge failed and was refusing to work.

     

    Under EU law blocking the work of 3rd party cartridges and making cartridges inoperable is illegal.

     

    I also fully documented the way on how to bypass easily HP DRM timebomb.

     

    1) Make sure printer is restricted from using internet and wifi, you can reset it before and set up it blocking future firmware updates.

     

    2) power off the printer

     

    3) set time on computer connected to the printer as Jan 1, 2018.

     

    4) Power on the printer.

     

    5) Old cartridge will work as a charm.

     

    6) The fact that simply changing the time makes "Failed" cartridge to work shows that HP using illegal DRM practice which violates EU law.

     

    before future printing set January 1st time, otherwise printer will get same error
