Claim:
1. A device, comprising: a first voltage generation unit configured to generate and supply a first voltage being used to driving a load to a power line supplying power to the load; a second voltage generation unit configured to generate and supply a second voltage lower than the first voltage to the power line; an acquiring unit configured to acquire a voltage value based on a voltage of the power line; a determination unit configured to perform a determination to determine whether an electronic state is in an error state based on a voltage value acquired by the acquiring unit, and a control unit configured to control the first voltage generation unit and the second voltage generation unit, wherein the determination unit performs a first determination to determine whether the electronic state is in the error state based on an amount of change of a first acquired voltage value acquired per determined time acquired by the acquiring unit under a condition in which the control unit controls the second voltage generation unit to supply the second voltage and the first voltage generation unit to stop supplying of the first voltage after starting supply of the first voltage with the first voltage generation unit, at a timing when a driving operation of the load is stopped after driving the load, and wherein the control unit causes the device to stop an operation in a case where the determination unit determines that the electric state is an error in the first determination.
