How to Make Enlarged Copies With an HP C3100 Printer

Verify that your HP C3100 printer is on and has paper in the input tray.
Open the top of the HP C3100. Place the document you want to copy face down on the glass so that the edge lines up with the front right corner.
Press the 'Size' button to change the size of the copy output. Select a size larger than 100 percent to enlarge the copy.
Press the 'Start Copy Black' button for a black and white copy. Press the 'Start Copy Color' button for a color copy. Retrieve your enlarged copy from the output tray when the C3100 ejects it.
