new firmware bricked M209DW printers in office

[drizuid]

I believe this is well known as it has impacted a huge number of users, even though HP is broadly downplaying it as limited.

the recent firmware release causes the printers in the m209 as well as the m232-237 series lines to recognize all cartridges as unofficial which prevents printing, regardless of any settings in the printer itself. I even purchased a new ink cart to ensure no issues and a brand new, direct from HP, cartridge was also recognized as not official and blocked.

We are also currently having this issue. Webpage says last firmware was completed on 2/5 and the printer fails to update firmware again. a genuine cartridge is in but there are no ink levels.  new ink cartridge printed for a day before the printer stopped printing again

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

I completely understand how frustrating this situation must be. It’s definitely not the experience we want you to have, and I sincerely regret the inconvenience this has caused.

Have you already tried any troubleshooting steps? If not, I’d recommend checking for new firmware updates.Update the firmware on an HP printer | HP® Support

Try to restart the Printer

1. Turn off the printer.
2. Unplug the power cord from the back of the printer.
3. Remove the cartridges.
4. Press and hold the power button for 30 seconds.
5. Plug the power cord back in.
6. Wai for few minutes and then insert the cartridges (let printer prompt for cartridges)
7. Turn on the printer

Also, resetting the printer to factory defaults might help. Restore factory defaults on your HP printer | HP® Support

Take care and have a good day.
