D Working with memory and print server cards Note Printer memory The printer has five dual in-line memory module (DIMM) slots. For maximum flexibility in DIMM support, the formatter is designed with four 168-pin DIMM slots and a fifth 100-pin DIMM slot. Due to technical limitations, only four DIMMs can be loaded at a time, so the fifth DIMM slot (100-pin) is logically the same as the fourth DIMM slot (168-pin). The system can only have a DIMM installed on the fourth DIMM slot (168-pin) provided that no DIMM is installed in the fifth DIMM slot (100pin) and vice versa. Use these DIMM slots to upgrade the printer with: z more printer memory - DIMMs are available in 64, 128, and 256 MB z flash memory DIMMs - available in 4 MB; unlike standard printer memory, flash DIMMs can be used to permanently store downloaded items in the printer, even when the printer is off z DIMM-based accessory fonts, macros, and patterns z other DIMM-based printer languages and printer options You may want to add more memory to the printer if you often print complex graphics or PS documents, or use many downloaded fonts. Additional memory also allows the printer to print multiple, collated copies at the maximum speed. ENWW 211
