I connected a different external monitor and it turns on but doesn’t display an image.

m Once you set the resolution for an external monitor, any other external

monitor subsequently connected to your PowerBook will attempt to use

that resolution. If you cannot set a resolution for the new external monitor

that results in an image on the screen, you may need to detach the second

monitor, discard the Display Preferences file (in the Preferences folder

inside the System Folder), reconnect that monitor, and choose a resolution

over again to see a satisfactory image. For instructions, see the Monitors

topic area of Mac OS Guide.)

Printers

The computer can’t find the printer.

m Make sure the printer is connected and turned on.

m The printer may not be selected in the Chooser. Open the Chooser and

select the printer you want to use. If the printer is connected to a port,

make sure the correct port is selected.

m Reset the parameter RAM. (See “The Computer Makes an Unusual Sound

at Startup, or You See a ‘Sad Macintosh’ Icon” in the section “Problems

Starting Up the Computer” earlier in this chapter for instructions.) Then

select the printer in the Chooser and try printing again.

The printer does not appear in the Chooser.

m Make sure you’ve selected the correct kind of printer on the left side of the

Chooser window. For example, if you’re using a StyleWriter II, make sure

to select StyleWriter II, not StyleWriter.

m Use the scroll bars to look through all the selections in the Chooser

windows.

m Check the connections between your computer and the printer, including

relevant sections of the network if appropriate. (See “Problems With

Networks and File Sharing” later in this chapter.)

m Make sure the correct printer software is in the Extensions folder inside

your System Folder.
