Lexmark MC2425

Unable to downgrade code

Explanation

Code may not be able to be downgraded below manufactured level. If a code level older than the manufacturing code is flashed, device does not accept code. Programming Failed Invalid Version shows briefly on the screen, then printer restarts without changing code level.

Issue can affect devices with manufacture date of 2021 or newer. Manufacturing date is on a label inside the front door of the printer for most models. On some models, remove the paper tray to see the label. Device may also be affected if components have been replaced in a service action.

Due to the worldwide shortage of integrated circuit (IC) chips caused by the COVID-19 pandemic, Lexmark has had to find alternate components to continue production. Most of these hardware changes do not require special firmware. A limited number of hardware changes do require firmware changes to ensure functionality.

Solution

Do not downgrade firmware.

Lexmark does not officially support downgrading firmware, however if you choose to do so, please refer to Consequences and precautions to consider before deciding to downgrade firmware for important information.
