Apple LaserWriter 12/640 PS - Manual (Page 238)

238 Chapter 12
No LaserWriter 8 icon appears in the Chooser.
Make sure that the LaserWriter 8 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 computer.
The printer is not listed in the Chooser.
If you’ve selected the LaserWriter 8 icon but your LaserWriter 12/640 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 Ready light to turn on.
m The communications settings are not set correctly. See “Adjusting
Communication Settings” in Chapter 1 and Appendix A. See also
Appendix D for a list of acceptable values. To reset the communications
settings to their factory default values, set the communication switch to the
Reset (out) position. Turn the printer off and back on again. Set the
communication switch to the Normal (in) position.
m Someone may have renamed the printer. Check the startup page to see if
the name has changed.
m If you are using an AppleTalk network that contains zones, you may not
have selected the correct zone for the printer.
m There’s a problem in the network cable system somewhere between your
computer and the printer you want to use. Make sure that all the cables are
properly connected. If you still can’t resolve the problem, the printer’s
electronics or the network connector boxes may not be functioning
properly. Call an Apple-authorized dealer.
