Firmware for OfficeJet 6500A - Downgrade

[mrkos]

Dear Sir

I have an HP OfficeJet 6500A All-in-One printer that stopped working with compatible ink cartridges after automatic upgrade to the latest firmware .

I consider that the situation is illegal in terms of law, because it was without my consent and the printer is owned by me and not owned by HP.

I would like to do a firmware downgrade or alternatively that HP will provide me with a new firmware that will fix this problem.

This one FW: https://support.hp.com/us-en/drivers/selfservice/hp-officejet-6500a-e-all-in-one-printer-series-e710...
i can´t downgrade.

Carefully,

Stepan

Sorry, that printer never had the firmware security issue what was fixed.

This Post pertains to the following OfficeJet products listed in the following table that has new firmware that disables the cartridge security affecting cartridges using Non-HP security chips.  If your printer is not listed here, it is not affected.

OK, so how can i downgrade FW for my Printer?
Because after update is not working because of non-original cartridges.

Thank you.

I don't see any firmware upgrade.  Last time was in 2016.

Just to add to sabertooth04's posts, the lastest release for the HP Officejet 6500 e710 was released in November of 2016.  The firmware version is CIP1FN1621AR.  You can confirm that your printer is running that version of firmware by looking at the printer's web pages, or by printing the Printer Status Report.

We typically don't recommend downgrading firmware once an update has been installed.  There can be unintended side effects when one does so.  The 1621A firmware release focused on several networking security enhancements, and compatibility with the Microsoft Edge and I.E. 11 web browsers.

Hello,

The hp AIO 6500A (e710) is not on the table you sent, and the last firmware for it is indeed from 2016 (CIP1FN1621AR), but after the firmware was upgraded to that firmware the printer doesn't work at all, and just shows the message: "The Printhead installed is not intended for use in this printer, or is damaged" - only because there are compatible ink catridges in it.

I also understand that you don't recommend to downgrade the firmware, but it is the only way to make the printer work (except to buy a very expensive original ink catridges).

so please let us know:

HOW DO WE DOWNGRADE THE FIRMWARE OF THE PRINTER ?   or:

HOW DO WE CANCEL THE UPGRADE OF THAT FIRMWARE ?   or:

HOW DO WE RETURN THE PRINTER TO THE FACTORY ORIGINAL FIRMWARE ?

FYI:

(1) For some reason HP doesn't include in it's website previous firmware beside that mensioned above, and there was no archieve found of previous versions of any HP software - and it seems it's on purpose.

(2) I have a technical background and only after a very long search I found on other website older version of the printer firmware, but when I tryed to install it I got a message that it's not applicable - well done, HP programmers prevented even that, so the users will have to buy a very expensive original ink catridges.

(3) I used those catridges untill the firmware was updated and they worked fine; I used similar catridges before those and they also worked fine; I am still using similar catridges on another printer (that it's firmware was not updated) and they also work fine - so don't bother to relate them in your answer.

I expect a fast and efficent answer and not another evasive one, because the printer is completely disabled.

Thanks.
