A new firmware update has rendered some HP LaserJet printers inoperable, even when using HP’s own toner, Ars Technica reports. The update, version 20250209, was released on March 4, 2025 for HP’s LaserJet MFP M232 to M237 series.
According to HP, the update includes security enhancements, updates to meet regulatory requirements, and general improvements and bug fixes. There’s no mention of any changes to how the printers handle HP toner.
Despite this, users have started reporting Error Code 11 and a flashing toner indicator after updating their printer firmware. On HP’s support forums, frustrated customers are reporting that their printers with HP-branded toner have suddenly stopped working, despite attempts to clean the connectors and reinstall the toner cartridges.
HP has acknowledged that a problem exists, with a company spokesperson commenting: “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: https://support.hp.com.”
However, HP hasn’t confirmed how many users are affected, and the exact extent of the problem remains unclear.
This is far from the first time HP firmware updates have caused havoc for users. In May 2023, an update caused several HP OfficeJet printers to stop working completely and display a blue screen for weeks.
HP also has a controversial policy of blocking printers that use non-original ink and/or toner, which has been criticized by both customers and consumer organizations. The company has also been criticizes for its shady business models, like always-online printers and subscription ink.
