Neatly place the originals face up in the
original supply tray.
The originals are ready for scanning.
– Do not add or remove originals while they are
being scanned.
– When scanning is complete, remove the
originals from the originals delivery tray to
avoid paper jams.
– Avoid using feeder to scan the same originals
more than 30 times. When scanned repeatedly,
originals can become folded or torn, which
may cause paper jams.
