Service Check Points Periodic replacement parts are the parts that should be changed at regular intervals. Failure of these parts can seriously affect the printer’s performance. These parts should be replaced during a regular service visit closest to the end of the part’s expected life. The following parts should be replaced after approximately 150,000 pages of use: • Fusing Assembly • Transfer Roller • Separation Pad • Pickup Rollers (Tray 1, Tray 2, and Tray 3) • Output Feed Rollers (Upper and Lower) • Transport Belts and Rollers See Chapter 7: Removal and Replacement for procedures on removing and replacing these parts.
Variables such as media, environment, and usage can cause premature wear of these parts. See Chapter 2: Operating Requirements for information on suitable media, environment, and usage conditions. 58 4 Printer Maintenance C4170-90959
