摘要： Disclosed are a method of preventing overheating of a fuser assembly (100) and an apparatus using the same. The method of preventing overheating of a fuser assembly includes inspecting whether a temperature of a fuser assembly (100) is higher than a predetermined temperature. If the temperature of the fuser assembly (100) is higher than the predetermined temperature it is determined whether there is a print command. A print sheet is passed through the fuser assembly, and conveyed to a predetermined location. The temperature is again inspected if there is no print command. If the temperature is lower than the predetermined temperature it is determined whether a predetermined time has lapsed. The temperature is again inspected if the predetermined time did not lapse.

摘要： In a conveyance path made up of guide plates which guide a copy sheet to the transfer region between the photoreceptor and the opposing transfer device and a second guide plate for conveying the copy sheet to the fixing rollers, the guide plates and the fixing rollers including the pre-fixing guide, which all will be in contact with copy sheets, are grounded via a common resistor having a high resistance. An adjuster resistor is interposed in series between the common resistor and the guide plates positioned before transfer which are closer from the transfer region compared to the fixing rollers. When a copy sheet resides across the transfer region with both sides in contact with the guide plates and fixing rollers or with one side in contact, the total current that flows during a transfer operation is practically determined by the common resistor which has a high resistance. Accordingly, the flowing current can be limited within a certain range, thus it is possible to stabilize the transfer potential and hence to achieve a stabilized transfer operation.
