User-installable accessories The user can purchase and install accessories that expand or enhance the printer's capabilities. Memory upgrade CAUTION Static electricity can damage the dual inline memory modules (DIMMs). When you handle DIMMs, take either of the following actions: wear an antistatic wrist strap -Orfrequently touch the surface of the DIMM's antistatic package and 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 you add more memory. 1 Turn the printer off. Unplug the power cord and disconnect any cables. Note If an optional duplexer is installed, you will first need to remove the rear section and the cable tray (see "If an optional duplexer is installed:" on page 108). 2 Loosen the two captive screws on the back of the printer. 3 Grasp the screws and pull the formatter board out of the printer. Place the board on a flat, nonconductive surface. 4 Remove the DIMM from the antistatic package. Hold the DIMM with your fingers against the side edges and your thumbs against the back edge. 5 Align the notches on the DIMM with the DIMM slot. (Make sure that the locks on each side of the DIMM slot are open, or outward.) 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 open.) Q1860-90918 6 Removing and replacing parts 107
