To turn on accessories on (Mac OS X)

the printer software. If you add a new accessory later, follow these steps:
Open the System Preferences and then select Print & Fax or Print & Scan.
Select the printer from list of printers, and then click Options & Supplies.
Click the Driver tab.
Select the options you want to install, and then click OK.
