Increasing the printer RAM

You can increase the memory size of the LaserWriter 12/640 PS. You can install up to 64 megabytes (MB) of random-access memory (RAM) in the printer to provide faster performance on complex documents, documents containing many fonts, and duplex printing. You can also enable the printer’s PhotoGrade feature, which provides enhanced printing of graphics, by increasing the printer’s memory to 12 MB of RAM or more.

Adding RAM allows more fonts to be downloaded to the printer at one time; provides more space to store the calculations needed for large or complex images; increases the space available for font caching, or maintaining recently used fonts in memory for faster access the next time they are needed; and enables duplex printing.

IMPORTANT The instructions provided here explain how to install added memory in your printer yourself. If you wish, you can also contact an Apple- authorized dealer to install more memory for a service fee.

You can purchase additional RAM for the LaserWriter 12/640 PS in units of 4, 8, 16, and 32 MB. You can purchase 4 MB RAM expansion kits from Apple-authorized dealers. You can also purchase RAM expansion kits from many electronics and computer outlets. For information about the RAM specifications required to expand your printer’s memory, see Appendix D.

IMPORTANT The RAM used in the LaserWriter 12/640 PS is not the same type of RAM used in earlier LaserWriter II printers. The two are not interchangeable.
