Reference Information 7.5 Installing Accessories 7.5.1 Precautions When Installing Printer Accessories Never remove the control board cover while the printer is plugged in. To avoid the possibility of an electrical shock, always disconnect the power cord when installing or removing ANY internal or external printer option. The control board and internal accessories (wireless network interface card, DIMM, and hard disk) are sensitive to static electricity. Before installing or removing internal accessories, discharge static electricity from your body by touching something metal, such as the metal back plate on any device plugged into a grounded power source. If you walk around before finishing installation, discharge any static electricity once again. 7.5.2 Installing Printer Memory Additional printer memory is provided on a Dual In-line Memory Module (DIMM). The Dell 5330dn Mono Laser Printer has 256 MB of memory. It can be expanded to 768 MB. NOTE: Your printer supports only Dell DIMMs. Order Dell DIMMs online at www.dell.com. 1. Power the printer off and unplug all cables from the printer. 2. Grasp the control board cover and remove it. 3. Remove a new memory DIMM from its antistatic package. 7-6 Service Manual
