3) Before setting documents, sufficiently loosen them.
For details, see Section 3.2.2, "Setting Documents."
4) Set the documents on the document support.
− Estimate the number of pages to be set based on the following
standard:
The document thickness must be 4 mm or less (50 sheets by
55 kg/ream (64 g/cm2) paper) for A4 or legal size or smaller.
− Level the end of documents to be set.
For details, see Section 3.2.2, "Setting Documents."
− Set the documents as follows.
◊ For single-side reading: Place the reading side facing down
(document support surface).
◊ For double-sided reading: Place the surface (first page)
facing down (document support surface).
− Insert the documents in the automatic document feeder until they
softly touch the back of the automatic document feeder.
Excessively strong insertion results in feeding multiple pages
simultaneously. Also, make sure that the ends of the pages are not
folded down.
5) Adjust the document guides to the document width, then straighten
the documents.
If the documents are placed loosely between the left and right guides,
they may be read diagonally.
6) Switch the reading mode by pressing the Duplex button.
When the Function No. display panel is ON, the single-side reading
mode is active.
When the Function No. display panel blinks, the double -sided reading
mode is active.
