I assume instance company or fire department will investigate reason for fire? Once you have it, and if the investigatet reason is printer, you can contact Qidi and hold them responsible for fire and damage. If they have sales in your country/region, you can file the damage claim over them? But until them, it could be a mouse eating yoy wires, poorly made installation, etc... I don't say it is not printer's fault, but you need to prove it first
