Mine is Laser monochrom.
Bought new in 2013 for 160€, used less than 10 toner cartridges (generic one for 10€ each).

Printed several thousands of pages.
Only needed it a few times a year though.

P.S. if you want it new, can still be bought for less than 200€ if in stock

Firmware update bricks #HPPrinters, makes them unable to use HP cartridges

HP already has a reputation for breaking printers with updates.

Scharon Harding – Mar 10, 2025 2:05 PM

"HP, along with other printer brands, is infamous for issuing firmware updates that brick already-purchased printers that have tried to use third-party ink. In a new form of frustration, HP is now being accused of issuing a firmware update that broke customers’ laser printers—even though the devices are loaded with HP-brand toner.

The firmware update in question is #Version20250209, which HP issued on March 4 for its LaserJet MFP M232-M237 models. Per HP, the update includes 'security updates,' a 'regulatory requirement update,' 'general improvements and bug fixes,' and fixes for IPP Everywhere. Looking back to older updates’ fixes and changes, which the new update includes, doesn’t reveal anything out of the ordinary. The older updates mention things like
'fixed print quality to ensure borders are not cropped for certain document types,' and 'improved firmware update and cartridge rejection experiences.' But there’s no mention of changes to how the printers use or read toner.

"However, users have been reporting sudden problems using HP-brand toner in their M232–M237 series printers since their devices updated to 20250209. Users on HP’s support forum say they see #ErrorCode11 and the hardware’s toner light flashing when trying to print. Some said they’ve cleaned the contacts and reinstalled their toner but still can't print.

"'Insanely frustrating because it's my small business printer and just stopped working out of nowhere[,] and I even replaced the tone[r,] which was a $60 expense,' a forum user wrote on March 8.

"When reached for comment, an HP spokesperson said: 'We are aware of a firmware issue affecting a limited number of HP LaserJet 200 Series devices and our team is actively working on a solution. For assistance, affected customers can contact our support team at: support.hp.com."

If you have a HP LaserJet 4000, 4050, 4100, or 4150 (likely others) and are attempting to replace the transfer roller (under the toner cartridge) as part of maintenance, please note the fragility of the small plastic clips that hold it in place. While the printer is a workhorse, it's full of brittle plastic :-(

Ask me how I know (now).

What's up, home? part 44: Can ChatGPT help setting up Zabbix monitoring an USB-connected HP LaserJet? Well.. maybe!

By day, I am a Lead Site Reliability Engineer in a global cyber security company, Forcepoint. By night, I monitor my home with Zabbix & Grafana Labs and do some weird experiments with them. Welcome to my blog about the project.
