Removal and replacement strategy

This chapter describes how to remove, replace, and reassemble the major assemblies of the digital sender. Replacement is generally the reverse of removal.

WARNING! Unplug the power cord from the power outlet (at the wall receptacle) before attempting to service the digital sender. If you do not follow this warning, severe injury can result. Certain functional checks during troubleshooting might require power to be supplied to the digital sender. However, all power should be turned off and the product should be unplugged when you remove any digital sender assemblies or components. Never operate or service the digital sender when the protective cover is removed from the laser/scanner assembly. The reflected beams, although invisible, can damage your eyes.

CAUTION: The product contains components that are sensitive to electrostatic discharge (ESD). Always perform service work at an ESD-protected workstation. If an ESD-protected workstation is not available, discharge body static by grasping the digital sender chassis before touching an ESD-sensitive component. Ground the digital sender chassis before servicing the digital sender.

NOTE: To identify the left side and right side of the digital sender, face the control panel.
