Error Code 11 - M234DWE - Genuine Toner suddenly stopped working. Unable to clear error

[K-Med]

Yeah, this is just a bad look for HP all around. We're just the ones that noticed it and know how to post on a forum. Imagine how many 1,000s of other users are being affected by this and just think their printer broke.

Anyone that tried the firmware link they posted - did you also get a code "49" on your LCD panel?

Now I cannot even access the printer via the web interface anymore.

Can you please post the executable for the proper version - even if it's the bugged 20250209?

Thanks.

Or is there a link anywhere that actually works so I can browse via FTP the files available for this printer model? 

Bueller? Anyone?

I did not get code 49. It just did nothing. I rebooted and we're back to error 11 and the latest firmware for my M234dw

[H411]

Thanks for that - I unplugged the printer and it became accessible again - with Error 11. Same as you.

So it's bricked for now. I'm glad another user said they had the same issue with a brand new toner (saved me $65 plus a trip to Staples).

I went out and got a similar Brother printer for $144 at Walmart. Not ideal - but no more auto firmware updates - plus the new printer has it's own 250 sheet paper tray and manual sheet feeder which is nice. Just a little bigger than the HP. It's a little slower first page out - but I'm not in any particular hurry.

Anyone want to buy a used HP MFP-M235dwe? Only 500 pages printed!

[K-Med]

You're welcome. I'll just be using my office printer until HP decides to fix or replace these bricked printers.

[H411]

I highly doubt there would be any restitution for rendering the printers (we paid for) useless. Nothing beyond a weak "we're sorry about that" and maybe a 10% off coupon on their subscription plan. 

Sad state of affairs when this is all we expect out of these monolithic mega-corporations. Totally lost touch with the consumer.

PS - what they *should* be doing asap - is pushing out the previous version to every single printer that got the new version. Don't they test these firmware updates in-house before sending them to the public?

[K-Med]

They definitely did not test this and you're absolutely right, they make not do right by us and just ignore this completely.

Seems like a lot of us had the same ER11 problem at the same time frame.  Could it be linked to a firmware upgrade and caused a problem?  My firmware date code is 20250209.

Sure is. That firmware bricked all of our printers. We have no word from HP. I can't even put in a trouble ticket.

[MI_ScottK]

Me too.  I can’t even register my printer as their website will not recognize my product code and serial number.

Now, I can’t print my taxes!

It would be nice if there was a firmware version to revert back to.  If the newer firmware is not compatible with my M234sdw, then why was it pushed to my printer?
