HIGH VOLTAGE POWER SUPPLY WITHOUT OUTPUT VOLTAGE ADJUSTMENT, METHOD OF ADJUSTING OUTPUT VOLTAGE OF THE HIGH VOLTAGE POWER SUPPLY IN IMAGE FORMING APPARATUS, AND IMAGE FORMING APPARATUS USING THE METHOD

摘要

A high voltage power supply (HVPS) without an output voltage adjustment, a method of adjusting an output voltage of a HVPS, and an image forming apparatus using the method are provided. The image forming apparatus includes a high-voltage output unit that outputs a high voltage produced by the HVPS, a tag that stores an offset voltage information and is attached to the HVPS, and a high-voltage output control unit that reads the tag attached to the HVPS to extract the offset voltage information, and corrects a high-voltage output control signal by using the offset voltage information to change the high voltage output by the high-voltage output unit. Accordingly, a process of adjusting an output voltage of an HVPS as a single component is not required. The manufacturing costs of HVPSs are reduced, and the process of finely adjusting an output voltage of the HVPS is simplified.
