I was upgrading Firmware on my Laserjet 500mfp M525 and there was power cut, after, when I try again, it comes on the display panel “Error, Communication Lost”… Please, help me fix it….
If upgrading firmware - is acceptable procedure for this type for machine and can be done by regular user - then you probably can be covered by vendor warranty and need to call to official HP service company nearest to you.
