Choosing originals to scan
The document feeder is designed to accept standard office papers as
originals. Like a copy machine, the document feeder may have problems with
bent, torn, or otherwise mutilated originals.

These originals work best

The document feeder accepts paper with the following dimensions and
weight:
mpaper size
length 10 1/8 to 14 in. (257 to 356 mm)
width 7 3/16 to 8 1/2 in. (182 to 216 mm)
mpaper weight 16 to 20 lb. bond (60 to 160 g/m2)

These originals may cause trouble

The document feeder will not work well with
moriginals with tears, perforations, or punch holes
mcurled or wrinkled originals
mcarbon-backed originals or originals on coarse paper
mlabels or postcards
mthick, taped, or glued originals
Such originals will work fine if you place them directly onto the scanner,
rather than feeding them through the document feeder.

Avoid valuable documents

Apple recommends that you avoid using the document feeder to scan valuable
originals. Some important documents, certificates, and photographs fall
within the acceptable limits for size and weight and can therefore go through
the document feeder for scanning. You should be aware that paper jams
sometimes occur, and such jams may damage a document. See “Bypassing the
Document Feeder,” later in this chapter, for information about scanning
without the feeder.
