Good Morning! To extract a file you need to use any archiver. For example, WinRAR or other...

With the printer powered on, remove the power cord from the back. Wait 2 minutes. Plug back in the power cord and power it on. Do you still have the error?

Hi! Unfortunately, there is no firmware for this model and it will not be developed in the near future either. We're very sorry to say that.

You need to install the firmware in normal mode (using the power button only). You do not need to put the printer into update mode by pressing a button combination.
