1 To clear staple jams from the optional stapler/stacker Note Clear staple jams when the message JAM IN STAPLER appears on the printer control panel display. 1 On the right side of the stapler/stacker, turn the stapler unit toward the front of the printer until the unit clicks into the open position. Pull 2 outward on the blue staple cartridge to remove it. 2 Rotate the green cover on the end of the staple cartridge upward and remove the jammed staple. 3 Insert the staple cartridge into the stapler unit and rotate the stapler unit toward the rear of the printer until the unit snaps into place. The stapler needs to reload after clearing a staple jam, so the first few documents (up to five) might not be stapled. If a print job is sent and the 3 stapler is jammed or is out of staples, the job will still print as long as the path to the stacker bin is not blocked. ENWW Clearing jams 107
