The Lexmark Universally Adjustable Tray (UAT) enables you to feed quantities of custom-size media that range in 1 mm increments from 76.2 mm x 127 mm to 215.9 mm x 355.6 mm (3 x 5 in. to 8.5 x 14 in.). The minimum size supported in the 250-Sheet UAT is 3x5 inches. 3x5 inch setting is not supported if other options are installed above the UAT. This size setting formats the page for 215.9 x 355.6 mm (8.5 x 14 in.) unless the size is specified by the software application.
