Removal and Replacement Strategy This chapter describes the complete disassembly of the printer. In every instance, tasks that must be performed before beginning the procedure are listed first. Remove the assemblies in the order listed to prevent damage during re-assembly. To ensure optimum print quality, the printer will prompt to have routine maintenance performed every 200,000 pages. When the message PERFORM PRINTER MAINTENANCE appears on the Control Panel, the Printer Maintenance Kit must be installed. See page 4-5. Servicing the printer involves replacing printed circuit and electro-mechanical assemblies. Do not repair component failures within these assemblies.
In all instances, replace the failed assembly. The replacement procedure is the reverse of the removal procedure, except where specific instructions are provided. WARNING! Some sheet metal edges, particularly around the formatter cage, are sharp. Be careful when working in these areas to avoid cutting yourself. CAUTION The printer contains parts that are sensitive to Electrostatic-Static Discharge (ESD). Always observe proper ESD procedures when servicing the printer. The ESD symbol appears in this chapter when the parts being serviced are especially susceptible to ESD damage. It is usually best to remove and replace the covers in the order shown.
Turn the printer off and unplug the power cord and any cables. 6-2 Removing and Replacing Parts
