![]() ![]() This section contains current firmware versions (as officially supplied by HP) for any printers that can have dynamic security removed. For printers with a physical control panel, the same option can be selected from the "update printer" setting here.įor very old printers you may need to uninstall the update software, which is a separate installation to the driver.įor detailed instructions, see our article here. Most reliable is to use the printer's internal control panel - open a browser tab and type in the printer's IP address, then turn off "auto update" in the settings menu. Please note that turning off firmware updates will stop any new ones from being applied, but will not reverse the effect of an existing update. Since technically the cartridges are fit for the purpose for which they were sold at the time of the transaction, and they don't work now because of a change in the circumstances in which they are being used, there is no legal requirement for them to be considered faulty under warranty.Īll automatic updates can be turned off, but the exact process depends on the age and functionality of the printer. Other retailers may have different return policies. Please get in touch with our customer service team to arrange a return authorisation before sending anything back to us. You can return your cartridges (including partially used items) for replacements if we have them, or if not, for credit towards either replacements when they arrive, or OEM cartridges (which will be more expensive, so there will be a price difference to pay). We may not have replacement stock for a short while after a firmware update, while we source cartridges with the new chip type, but we will make sure you are covered. If you bought them from us, and they are still within the warranty period (usually a year), then the answer is yes. If I can't reverse it, can I return the cartridges? Your best option is simply to prevent the next update causing the same problem - see here for instructions. In most printers made after December 2016, there is no realistic way to reverse a firmware update. However, more recent updates have not attracted the same attention, so without the public and media pressure to address the issue, HP have not been inclined to make later changes reversible. ![]() Following a negative media reaction to the updates released in September 2016, HP made downloadable versions available that would roll back the changes to the dynamic security feature. This controls how the printer talks to cartridges, so if the chip on your cartridge is designed for an older version of the firmware, the printer won't be able to communicate with it, and will report it as missing or damaged. HP issue updates for a number of reasons, but the main effect is to alter their "dynamic security" feature. You can turn updates off, but the default setting is "on". You won't be notified before or after the update, and often the only way that you'll find out that it happened is that your cartridges will stop working. If your printer is on your WiFi network or is connected by cable to a computer with an internet connection, firmware updates can happen in the background. The programs running on this microprocessor are called "firmware" as opposed to "software" because they are semi-permanent and are not designed for user interaction. Your printer has a microprocessor inside - basically a mini computer - that makes it work.
