Feeding Methods
There are three feeding methods (feeder, flatbed, business card feeder) for scanning documents with this scanner. The types of documents that
can be scanned with each method are as follows.
Precautions for Using the Feeder
• When scanning a multipage document in a single scan procedure
using the feeder, make sure that all of the pages are identical in
thickness, and quality of paper. Feeding different types of paper at
one time may cause a paper jam.
• Scanning documents before the ink is dry will make the rollers and
scanning glass dirty, resulting in smears on the scanned image and
other documents becoming dirty. Always make sure that the ink on
a document is dry before scanning it.
• Scanning documents that are written in pencil or similar material will
make the rollers and scanning glass dirty, resulting in smears on the
scanned image.
• When scanning thin paper, text or images on the reverse side of the
page may bleed through onto the scanned image. In this case,
adjust the brightness under the scanning conditions.
• Always make sure to check that paper clips, staples, and similar
objects are not mixed in with a document before loading it into the
feeder. The presence of such objects may result in damage to
documents, paper jams, and damage to the scanner.
• Do not wear loose clothing or jewelry that may get caught in the
scanner while you are using it. Doing so may result in personal
injury. Be extra careful of neckties and long hair. If anything
becomes caught in the scanner, immediately disconnect the power
plug from the power outlet to stop the scanner.
