The 250-Sheet Legal Drawer from Dell is specifically designed for use with Dell Color Laser Printer 3000cn and 3100cn. It increases total paper input capacity to 900 sheets (when used along with an additional 500-sheet drawer) - helping reduce the number of times you refill the drawer. It installs beneath the printer. This drawer can be added for enhanced flexibility and unattended print jobs or printing on multiple paper types and sizes from different drawers
