*1 As the fixing roller is used more and more, its surface tends to become discolored because of heat. The change,
however, will not affect the performance of the roller. Also, note that the roller surface varies in color among
manufacturers and the fact will not affect the roller performance.
*2 As the pressure roller is used more and more, its rubber surface can start to discolor. The change, however, will
not affect its performance or output images. Further, the physical properties of the roller can permit its surface to
start to wrinkle. The roller, however, is free of wrinkles when it is heated and its performance will not be affected,
thus not requiring replacement.
*3 Replace simultaneously with fixing roller. When you replace bushings, apply about 20 mg of grease (Molykote
HP-300; CK-8012) on the inner and outer surfaces of the bushing until there is a white coating covering the entire
sources.
