User Installable Accessories 6-2 Removing and Replacing Parts Memory Upgrade CAUTION Static electricity can damage dual inline memory modules (DIMMs). When handling DIMMs, either wear an antistatic wrist strap or frequently touch the surface of the DIMM's antistatic package, then touch bare metal on the printer. If you have not already done so, print a configuration page to find out how much memory is installed in the printer before adding more memory. 1 Turn the printer off. Unplug the power cord and disconnect any cables. (If an optional duplexer is installed, you will need to remove the rear section and the cable tray first.) 2 Loosen the two captive thumb screws on the back of the printer. 3 Grasp the screws and pull the formatter board out of the printer. Place it on a flat, non-conductive surface. 4 Remove the DIMM from the antistatic package. Hold the DIMM with fingers against the side edges and thumbs against the back edge. Align the notches on the DIMM with the DIMM slot. (Check that the locks on each side of the DIMM slot are open, or outward.) 5 Press the DIMM straight into the slot (press firmly). Make sure the locks on each side of the DIMM snap inward into place. (To remove a DIMM, the locks must be released.) EN
