Introduction This chapter documents removal and replacement of field replaceable units (FRUs) only. Removal and replacement strategy Replace parts in the reverse order of their removal. Directions for difficult or critical replacement procedures are included. WARNING! The sheet-metal edges of the device can be sharp. Use caution when working on the device. NOTE Note the length, diameter, color, type, and location of each screw. Be sure to return each screw to its original location during reassembly. Incorrectly routed or loose cables can interfere with other internal components and can become damaged or broken. Frayed or pinched cables can be difficult to locate. When reconnecting the cables, always use the provided wire loops, lance points, or cable guides. Electrostatic discharge CAUTION The device contains parts that are sensitive to electrostatic discharge (ESD). Always service the device at an ESD-protected workstation, or use an ESD mat. Watch for the ESD symbol (shown at left) to identify the parts that are sensitive to ESD. Protect these parts by using an ESD wrist strap and by placing ESD-sensitive parts into protective ESD pouches. User-replaceable parts To remove and replace the pickup roller or separation pad, see Separation pad on page 189. ENWW Introduction 77
