Image forming device with mounted replaceable unit, method of checking operation in that image forming device, and storage medium storing operation checking program directed to that image forming device
When a unit containing a fuse is mounted, in response to detection of a potential indicating that the fuse has not been blown by a detection circuit, a current for blowing the fuse is supplied from a blowing circuit to the mounted unit containing the fuse, and operation of the blowing circuit is checked based on potentials detected by the detection circuit before current supply and after current supply, respectively. When a unit containing a non-blown component instead of a fuse is mounted, a current is supplied from the blowing circuit to the mounted unit containing the non-blown component, and operation of the blowing circuit is checked based on potentials detected by the detection circuit before current supply and during current supply, respectively, or potentials detected by the detection circuit before current supply and after current supply, respectively.
