Removal and Installation Introduction This chapter is a step by step guide to the removal and installation of the key components in the Printer. You may find it useful to tick off the steps as they are performed. Use the illustration at each procedure to identify the parts referred to in the text. The procedures appear in order of removal. So the whole machine can be stripped down by starting at the beginning of this chapter and working through the subsequent procedures. NOTE Before using this chapter to remove and/or replace a component or assembly, always make sure that you have performed the relevant service test for each component as described in 4, Service Tests and Utilities. If the test passes you will not need to replace the component. NOTE To install a component perform the removal procedures in reverse order unless a specific installation procedure is provided. NOTE After removing and/or replacing a component, the relative procedure will state whether any calibrations and/or tests are required (5, Service Calibrations). Safety Precautions (Safety symbols - Immediately after the table of contents.) Review WARNING and CAUTION symbols and instructions before you service the Printer. Follow these warnings and cautions for your protection and to avoid damaging the Printer. WARNING Serious shock hazard leading to death or injury may result if you do not take the following precautions: Ensure that the ac power outlet (mains) has a protective earth (ground) terminal. Switch the plotter off, and disconnect it from the power source prior to performing any maintenance. Prevent water or other liquids from running onto electrical components or circuits, or through openings in the module. 8-2 HP DesignJet 5000 Series Printers Service Manual
