Macintosh troubleshooting
If you are using the printer from a Macintosh computer, use this section for
troubleshooting tips.
The Chooser does not appear in the Apple (
K
) menu.
If the Chooser isn’t listed in the Apple menu, the System file on your startup
disk may be outdated, or you may have removed the Chooser from the Apple
Menu Items folder in the System Folder on your startup disk. You can obtain
the current system software from an Apple-authorized dealer.
Make sure that you have only one System Folder on your startup disk.
Can’t find the printer driver icon in the Chooser.
Make sure that the LaserWriter 8 printer driver is properly installed. The
printer driver may be on your startup disk but may have been moved to the
wrong location. If necessary, drag the driver into the Extensions folder inside
the System Folder.
Also make sure that you have only one System Folder on your startup disk.
Refer to the information that came with your Macintosh.
The printer is not listed in the Chooser.
If you’ve selected the LaserWriter 8 icon but your Color LaserWriter
12/600 PS is not named in the list of printers, one of the following may be
the cause:
m The printer has been turned off. Make sure it is plugged in and turned on,
and wait for the startup page to print.
m The communication settings are not set correctly. See “Adjusting
Communication Settings” in Chapter 1 and “Viewing and Changing
Communication Settings” in Chapter 2. See “Can’t Communicate With the
Printer,” earlier in this chapter.
