TOPIC

    I installed the optional duplexer on my LaserWriter 12/640 PS printer, but the duplex option is dimmed. How do I use the duplex option?

DISCUSSION

    In order to use the optional duplex accessory, you must have a minimum of 12MB of RAM in your LaserWriter 12/640 PS printer. The table below shows the options available depending on the amount of RAM you have installed. The LaserWriter 12/640 PS printer uses industry standard 72-pin SIMMs (70ns or faster). The Tech Info Library article titled "LaserWriter 12/640 PS: Memory Configurations" contains a complete list of possible memory configurations.

    RAM Installed
    Options Available
    4MB (Standard) None. You cannot access either PhotoGrade or duplex printing.
    12MB You can enable either PhotoGrade OR duplex printing.
    20MB You can enable both PhotoGrade and duplex printing. Duplex printing is available up to US letter.
    24MB and greater You can enable both PhotoGrade and duplex printing. Duplex printing is available for all paper sizes including US legal.


    Note: Additional memory also enables you to download additional fonts and provides greater document caching.
