Placing an Original in the Auto Document Feeder (ADF)
The ADF automatically scans multiple sheets of originals or two-sided originals at one time.
Once originals start to feed in, do not push or pull them.
Do not mix different size originals.
For details about the sizes of originals that you can place in the ADF, see the following:
If the originals described below are placed in the ADF, it may cause misfeeds, white lines, or black lines, or result in damage to the originals. Place these originals on the exposure glass.
Stapled or clipped originals
Perforated or torn originals
Curled, folded, or creased originals
Pasted originals
Originals with adhesive tape, glue or paste stuck to them
Originals with any kind of coating, such as thermal paper, art paper, aluminum foil, carbon paper, or conductive paper
Originals with perforated lines
Originals with indexes, tags, or other projecting parts
Sticky originals such as translucent paper
Thin or highly flexible originals
Thick originals such as postcards
Bound originals such as books
Transparent originals such as transparencies or translucent paper
When loading an original written by pencil on the ADF, the original may be dirty from by being scraped.
Correct an original that tends to curl before setting on the machine.
Take care so that multiple originals do not stick to each other and are not fed at once.
Do not set an original that is wet with correcting fluid or ink. The scanning glass will be stained and the stain will be scanned with the original.
Do not open the ADF's cover until the scanned originals are ejected into the original output tray. Doing so may cause a malfunction.
If you push originals into the ADF, a paper jam may occur. If a paper jam occurs, open the cover of the ADF and reduce the number of original pages that you place on the ADF. Alternatively, open the cover of the ADF and place the originals but do not push them forcibly.
Adjust the original guide 
to the original size.
Place the aligned originals squarely face up in the ADF.
Place the originals with the first page facing up.
Fan sheets before loading so that multiple papers do not stick to each other and are not fed at once.
Do not stack the originals beyond the limit mark.
To scan originals larger than A4
or 81/2 × 11, pull out the ADF’s extender on the original output tray.
The machine cannot detect the size of the original automatically. Specify the original size.
