How Do You Reset Supply Levels on a Mac After Replacing the Ink Cartridge?

1. Click the 'System Preferences' icon located in the dock. This icon looks like three gray gears.
2. Click 'Print & Fax' located in the 'Hardware' section of the window, then choose your printer in the window that pops up. The available printers are listed along the left side of the window.
3. Control-click the printer you wish to reset and choose 'Reset Printing System.' A dialog box will ask if you are sure you wish to reset the printing system. Click 'Yes.'
