Abstract

A laser scanning unit (LSU) identification method and an image forming device are provided. The image forming device includes a processor and a target LSU, where the target LSU includes a laser diode, a laser diode drive unit, a polygon mirror, and a motor. The method includes providing a signal related to a quantity of reflective surfaces of the polygon mirror to the processor by the target LSU; identifying the quantity of the reflective surfaces of the polygon mirror of the target LSU according to the signal related to the quantity of the reflective surfaces of the polygon mirror provided by the target LSU, and determining a control parameter of the target LSU according to an identified quantity of the reflective surfaces by the processor, thereby controlling the target LSU according to the control parameter; and operating according to the control parameter by the target LSU.
