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.
