Chapter 9 F-9-47 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 F-9-49 output images. Further, the physical properties of the roller can permit its surface to start to wrinkle.
Page 382 Chapter 9 As wear grows, the surface of the shutter may become discolored because of heat or show scratches because of friction. These symptoms, however, are least likely to affect the performance of the shutter. 11) Remove the 2 screws [1], and detach the core positioning plate (front) [2].

Page 459: Periodically Replaced Parts
Chapter 12 12.1 Periodically Replaced Parts 12.1.1 Outline 0009-5822 Some parts of the machine must be replaced on a periodical basis for the machine to maintain a specific level of performance. They must be replaced regardless of the presence/absence of external changes or damage, as the performance of the machine will be considerably affected once they fail. If possible, plan any replacement to coincide with a scheduled visit.
Page 460: Outline
Chapter 12 12.2 Durables and Consumables 12.2.1 Outline 0009-5829 Some parts of the machine may have to be replaced once or more over the period of machine warranty because of wear or damage. Replace them as needed by referring to the table of estimated lives (expressed in terms of the number of prints they make). The intervals indicated may vary depending on the site environment and user habit.
Page 461 Chapter 12 As of December 2004 Part name Part No. Q'ty Life Remarks *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.
Page 462: Scheduled Servicing Basic Procedure
Chapter 12 12.3 Scheduled Servicing Basic Procedure 12.3.1 Scheduled Servicing Basic Procedure 0009-5839 - 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).
