Hello everyone,

I recently updated the firmware on my WF-7840 printer, and ever since then, I have been experiencing a lot of issues with it. The printer is not functioning properly, and it is causing a lot of frustration for me. I have heard that downgrading the firmware might resolve these problems, but I am not sure how to do it. Can anyone provide me with some guidance on how to downgrade the firmware on the WF-7840 printer? Your help would be greatly appreciated.

Thank you.
