To make use of specialized graphics features,fonts, and other applications on the market today, you mayfind it necessary to increase memory size.From the factory, the 4520 is equipped with 4 MB of residentbase memory. The 4520mp is equipped with 4 MB of residentbase memory plus one 4 MB SIMM (single in-line memorymodule) for a total of 8 MB.Maximum memory capacity is 52 MB.When is more memory needed?• You receive out-of-memory error messages whenprinting. See Chapter 3: Using the Control Panel,“PrinterSettings that Affect Memory” (page 3-69) for moreinformation on how certain printer settings may affectmemory usage and performance. See also “MinimumMemory Requirements” (page 3-72).• You determine that expanded capability for additionalfonts, more complex documents, graphics, or higherresolution is needed. See Chapter 4: Using Fonts,“Downloading Fonts” (page 4-12) for more information onhow fonts affect memory usage.How is more memory added?• Install a SIMM (single in-line memory module). SIMMsare small circuit boards with memory chips that can beinstalled on the printer controller board. SeeChapter 5: Adding Printer Options for more informationon SIMM installation.Installing the 125 MB hard disk option does not add memoryto the printer.MemoryConsiderationsWUG-CH01 Page 6 Black,Red,Cyan Sunday, January 22, 1995 7:30 PM
