Hi!  @Kamp75, Welcome to HP forums!

I understand after upgrading the firmware on your printer you are unable to use the refilled inks.

Don't worry I'll try to help you out.

Did you make any changes to your printer?

I have checked few records found few articles about why the refilled ink cartridges don't work.

HP is constantly improving security for its products and customers. Beginning in late 2015, HP implemented updates to the firmware related to the security chip in HP OfficeJet, OfficeJet Pro and OfficeJet Pro X printers that maintain secure communications between the cartridge and the printer. The purpose of this update is to protect HP’s innovations and intellectual property. These printers will continue to work with refilled or remanufactured cartridges with an Original HP security chip. Other cartridges may not function. In many cases this functionality was installed in the HP printer and in some cases, it has been implemented as part of an update to the printer’s firmware.

Here's the thing, yes, you can refill your cartridges or use remanufactured cartridges, but you may run into problems.
 
QualityLogic, one of the world's foremost quality assurance organizations, tested the performance of HP inkjet print cartridges vs. remanufactured (refilled) brands. The results: original HP inkjet print cartridges far surpassed ink refills in both print quality and reliability.
Nearly one out of every six refilled ink cartridges tested was dead on arrival or failed prematurely
70% of refilled cartridges had some form of reliability problem
Count on HP original ink cartridges for consistent, worry-free printing. You may think you're saving money on remanufactured or refilled ink cartridges, but in the long run, the cost of wasted time, ink, and paper can more than make up the difference.

However, you can try the following document to troubleshoot ink cartridge issues.

Hope to hear from you soon!

Have a wonderful day ahead! 🙂

this dosn't solve anything, i have a deskjet 1510 and when we talking about the price make the calculation your self

oreginal 301 cartridge cost 15.80 average with printet 226 pages = 0,07 cost ink per page 

the one i use till now cost 9.93 with 70ml printet 411 pages = 0,024 cost ink per page 

3x times higher price per page is not economy, its money trown out the window.

on the other hand when i was updating the softwore there was no information in bugfix ore changing information page about it. otherwise i wold never updatet the software on current version and would have searched a older one.

why i was updating the software is simple, the cd deliverd with the printer was not working, false version on the disk. 

CD Version 7.3.0 - Q5888-10023 -42640

The only think you want is incrising your product selling to a price who is way to high.
