Your automatic document feeder is designed to handle most paper types. However, if you are unsure 
if your document will cause a jam in the document feeder, we recommend that you scan it using the 
scanner glass (flatbed).

Paper with clip or staple

Paper with ink that is not dry

Paper with inconsistent thickness, such as envelopes

Paper with wrinkles, curls, folds, or tears
