6.1MAINTENANCE GUIDELINES

In order to minimize the complexity of troubleshooting and repairs, the V8.5e plotter is composed, wherever possible, of field- replaceable units (FRUs). The Imaging Systems Group Inc. does not recommend troubleshooting at a component level, but rather to the level of these FRUs. This chapter and the troubleshooting chapter of this manual follows this approach, resulting in faster and easier repairs. Replacing or repairing FRUs, rather than smaller components, minimizes downtime and simplifies procedures.

Use caution while troubleshooting the V8.5e. Turn the power off and unplugthepowercordtopreventelectricalshock.

Seien Sie bei der Fehlerbehebung am V8.5e vorsichtig. Schalten Sie den Strom ab und ziehen Sie den Netzstecker, um Stromschläge zu vermeiden.
