Clearing Staple Jams
Gently push the saddle stitcher unit back into its original position.
Close the front cover of the finisher.
CAUTION
When closing the front cover of the finisher, be careful not to get your fingers caught,
as this may result in personal injury.
IMPORTANT
When you have cleared the staple jam, be sure to manually reposition the staples in the saddle
stitcher unit. (See "Saddle Stitch Staple Repositioning," on p. 4-66.)
