Manage memory The MFP has two double data rate (DDR) DIMM slots to provide more MFP memory. DDR DIMMs are available in 64, 128, and 256 MB, for a maximum of 512 MB. The MFP has two compact flash slots to provide the following features: ● To add flash-based memory accessory fonts, macros, and patterns, use the appropriate DDR DIMM. ● To add other flash-based printer languages and MFP options, use the appropriate DDR DIMM. NOTE: Single in line memory modules (SIMMs) used on previous HP LaserJet products are not compatible with this MFP. For ordering information, go to www.hp.com/support/ljm9059mfp. Determine memory requirements The amount of memory you need depends on the types of documents you print. Your MFP can print most text and graphics at 1200 dpi FastRes without additional memory. You might want to add more memory to the MFP if you often print complex graphics or PS documents, print two-sided documents (duplex printing), use many downloaded fonts, or print large paper sizes (such as A3, B4, or 11 x 17). Install memory Use this procedure to install additional DDR memory DIMMs. Before you begin, print a configuration page to find out how much memory is installed in the MFP. The following table lists the maximum amount of memory allowed for each DIMM slot.

If you have not already done so, print a configuration page to find out how much memory is installed in the MFP. 2. Slide the optional output device away from the print engine.
