Solving memory problems If your printer encounters a memory shortage when trying to print a job, it may post an error message (37 Insufficient Collation Area, 37 Insufficient Defrag Memory, 38 Memory Full, or 39 Complex Page), depending on the task it is trying to complete. See Understanding printer messages for more information about these and other messages. If these messages appear frequently, you probably want to install additional printer memory. If they only occur rarely, try reducing the following: • The number of pages in the job • The number of fonts or graphics on each page • The size of scalable fonts used in the document • The number of fonts or macros downloaded to printer memory • Deleting Held Jobs You may also try adjusting the following settings: • Print resolution to 600 dpi • Page Protect On from the Setup Menu • Resource Save Off from the Setup Menu Allocating memory A portion of printer memory is reserved for input buffers that hold print jobs sent from your software application. Your printer has an input buffer for each interface (parallel, serial, network, LocalTalk, or infrared). You can change the amount of memory allocated to each buffer, depending on your system requirements. For more information about using printer menus to allocate memory for each interface, see Using printer menus and select the interface menu you want information about. The size of the input buffers varies with the amount of memory installed in the printer. The following table lists the default size of the input buffers for each interface. If your printer is not using a particular interface, the allocated memory is reserved for job processing. For more detailed information about these input buffers and memory allocation, refer to the Technical Reference. Default input buffer size Installed memory 32MB Each parallel port 192KB1 Each serial port 150KB Each LocalTalk network port port 1MB 1MB Infrared port USB port 150KB 150KB 64MB 2MB 300KB 2MB 2MB 300KB 128MB 1 1MB allocated to standard parallel port if no optional adapter is installed. 300KB Flash memory You can add optional flash memory to your printer. If you frequently download fonts, macros, forms, or symbol sets to your printer, you may want to use flash memory storage rather than RAM. Resources stored in flash memory are not lost when the printer power is turned off. 275
