Before Installing the Printer Driver
This section describes the items that you should check before installing the printer driver. You should also
refer to this section if the printer driver cannot be installed.
Checking the Printer Status
• Confirm that the USB port of this printer and the computer are firmly connected with the USB cable.
Checking the Personal Computer Settings
• Terminate all running applications.
• Log on as the computer administrator. The installer will prompt you to enter the name and password

administrator who registered first.
Important
• When you upgrade from Mac OS X v10.7 to Mac OS X v10.8 or from Mac OS X v10.6.8 to Mac OS X
v10.7, all printer drivers that were installed will be deleted.
