Memory Module By installing a Dual In-line Memory Module (DIMM), you can increase printer memory up to 1024 MB. You may want to add additional memory if you are having difficulty printing complex graphics. This printer has two memory slots, but one slot has a 64 MB DIMM already installed in it at the time of manufacture. To increase printer memory more than 578 MB, you have to remove the original 64 MB DIMM first and then install two optional DIMMs. Note: The maximum expandable memory is 1024 MB. Follow these steps to install an optional memory module. w Warning: Be careful when working inside the printer as some components are sharp and may cause injury. c Caution: Before you install a memory module, be sure to discharge any static electricity by touching a grounded piece of metal. Otherwise, you may damage static-sensitive components. 200 Installing Options
