*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.
13.3 Scheduled Servicing Basic Procedure

iR5065 / iR 5055 / iR5075 / / /
- As a rule, provide scheduled servicing every 250,000 prints.
- Check with the Service Book before setting out for a scheduled service visit, and take parts for which replacement is expected.
- If the power plug is left connected for a long time in a place subject to dust, humidity, or oil smoke, a fire hazard is a possibility (i.e., the dust collecting around
the plug can absorb moisture, resulting in insulating failure). Be sure to disconnect the power plug on a periodical basis, and wipe off the dust and dirt collecting
around it.
<Work Procedure>
1) Report to the person in charge, and check the general condition.
2) Record the counter reading, and check the faulty prints.
