Problems with Mac OS X (continued)

When connected with a USB cable, the printer does not appear in the Macintosh Print Center after the driver is selected.

Cause

This problem is caused by either a software or a hardware component.

Solution

Software troubleshooting

Check that your Macintosh supports USB.

Verify that your Macintosh operating system is Mac OS X version 10.1 or later.

Ensure that your Macintosh has the appropriate USB software from Apple.

Hardware troubleshooting

Check that the printer is turned on.

Verify that the USB cable is connected correctly.

Check that you are using the appropriate high-speed USB cable.

Ensure that you do not have too many USB devices drawing power from the chain. Disconnect all of the devices from the chain, and connect the cable directly to the USB port on the host computer.

Check to see if more than two nonpowered USB hubs are connected in a row on the chain. Disconnect all of the devices from the chain and connect the cable directly to the USB port on the host computer.

NOTE

The iMac keyboard is a nonpowered USB hub.
