A media supply tray includes a cable (110) and pulley (120, 125, 130, 135) system attached to side paper guides (126, 128). Movement of one side guide causes the opposing side guide to move in the opposite direction. When the side guides are moved, a flag (112) attached to the cable moves and can be detected to provide accurate feedback to a printer regarding media size in the tray. Alternatively, a Bowden cable (200) can be attached to the side guides for enhanced accuracy in size sensing. |
