PURPOSE:To perform correction on the basis of a correction value when the state at the time of operation is read by measuring the irregularity on the hardware of a conversion mechanism at the time of a manufacturing inspecting process to convert the correction value to a numerial value and recording the numerical value on a non-volatile memory. CONSTITUTION:A detection apparatus 1 and a non-volatile memory 2 having a correction value recorded thereon are connected to the processing part (CPU) 3 controlling the operation of a printer and the value of the detection apparatus 1 and the correction value recorded on the non-volatile memory 2 are read at any time. The actual resistance values of the voltage dividing resistors 4, 5 of the detection apparatus 1 are precisely measured from the outside to preliminarily record the value of the correction value on the non-volatile memory 2 and, when driver voltage is read by the CPU 3, processing multiplying the correction value is performed by firmware to confirm an accurate value. |
