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