General Notes on Disassembly Service Parts Disassembly Caution Follow the steps of all disassembly procedures in the order given to avoid damaging printer components. 1. Before servicing the printer, switch Off the printer power, wait until the printer completely shuts down, and disconnect the power cord from the wall outlet. 2. Wear an electrostatic discharge wrist strap to help prevent damage to the sensitive electronics of the printer circuit boards. 3. Upon reassembly of printer components, be sure the components are all in their home positions, otherwise damage to the printer will occur. See Chapter 6 Adjustments, Home Position page 6-2 for information on the home positions. Special Notes Regarding Screws Used in This Equipment. Caution Screws in plastic are torqued to 12 in. lbs., metal to 15 in lbs., unless otherwise specified. The screws for the Printhead Restraints should be torqued to 6 in. lbs. Irreversible damage can result from over tightening the screws into plastic parts. ■ Always use the correct type and size screw; coarse thread, brass-colored screws into plastic and fine thread, silver-colored screws into metal. ■ Using the wrong screw can damage tapped holes. This applies to the yellow reverse-threaded screws on the Drum. ■ Do not use excessive force to remove or install either a screw or a printer part. If using a power driver to install a screw into plastic, start the screw by hand. ■ If you strip out threads in the plastic chassis, a silver-blue-tinted thread repair screw (included in the hardware kit) can be used to correct the problem. ■ If you remove a silver-blue-tinted thread repair screw during disassembly, replace the screw the same location or additional damage to the printer will occur. Warning Unplug the AC power cord from the wall outlet before removing any printer part.
