Apple 12/600PS manual Increasing the printer RAM

Using external hard disks from manufacturers other than Apple

IMPORTANT Some older model hard disk drives may not be compatible with the Color LaserWriter 12/600 PS.

If you are considering connecting external hard disks to your printer, keep these points in mind:

mThe printer requires SCSI 40 MB (or larger) hard disks.

mThe printer must be able to tell how much storage space is available on the disk. This is not possible with some hard disks from manufacturers other than Apple. You cannot use these disks with the printer.

mSome non-Apple disks have internal SCSI terminators. There should be no more than one terminator in addition to the one on the printer’s controller board (one on the first device in the chain and one on the last device).

mThe hard disk must be able to deliver at least 5 volts of termination power.

Increasing the printer RAM

The printer comes with 8 MB of RAM soldered on the controller board and a 4 MB SIMM in one of the two slots on the board. You can increase the memory size to a total of 40 MB (maximum) by installing up to 32 additional MB of RAM in the printer.

Adding RAM improves performance; 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; and increases the space available for font caching, or maintaining recently used fonts in memory for faster access the next time they are needed. Additional RAM also improves the image quality of documents printed on legal-size paper.

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.
