Introduction Removal and replacement strategy This chapter explains how to remove and replace major printer components. Replacement is generally the reverse of removal. Occasionally, directions for difficult or critical replacement procedures are included. Repair notices WARNING! Turn the printer off and disconnect the power cord before servicing the printer. Failure to follow this instruction could result in severe injury. Never operate or service the printer with the protective cover removed from the scanner assembly. The reflected beam, although invisible, can damage your eyes. The sheet-metal parts can have sharp edges. Be careful not to cut yourself when handling sheet-metal parts. CAUTION Always protect the imaging drum from light and physical contact when removed from the printer. HP recommends reinstalling the original cover whenever the drum is removed from the printer. Electrostatic discharge (ESD) The printer contains parts that are sensitive to electrostatic discharge (ESD). Watch for the ESD reminder shown at the left while removing printer parts. Protect the parts that are sensitive to ESD by using an ESD wrist strap and protective ESD pouches. 222 Chapter 6 - Removal and replacement EN
