Abstract

When a printing instruction is provided, a CPU causes a stepping motor M to drive a developer and calculates the value of a load of the stepping motor M before printing operations are performed. Then, CPU determines whether the value of the load is within a predetermined range stored in advance. If the value is not within the predetermined range, CPU causes a display to display an error message.
