To staple media by using the convenience stapler
1. Insert up to 20 sheets of media (80 g/m 2 or 20 lb) into the slot in the stapler door. Insert fewer
sheets to staple if the media weight is heavier than 80 g/m 2 or 20 lb.
CAUTION Do not use the convenience stapler to staple plastic, cardboard, or wood.
Damage to the convenience stapler can result from attempting to staple these materials.
NOTE Exceeding the recommended capacity could result in jams or damage.
2. Wait for the stapler to staple the sheets. When it is inserted all the way into the stapler slot, the
media should trigger the stapler mechanism.
