5.1.13PAGE OFFSETS (D)

Page Offset is a delay count used to accurately position the document at the scan window after loading ( using Auto scan mode ). The count varies with scanning resolution and scanning speed. When Page Offset is adjusted accurately, there will be no significant underscan or overscan and the margin appearing on the scanned image of the document will be the same size as on the actual document. The Page Offsets can be set either manually or automatically.

To set manually , press the <S> key and the prompt “RESOLUTION” will appear. Select one of the resolution indices ( a letter A-H ) appearing in the leftmost display comumn. Next , the prompt “FULL:“ will appear. Enter a four digit hex value to be used for the full speed page offset. Finally, the prompt “REDUCED:“ will appear. Enter the four digit hex value to be used for the reduced speed page offset. The values entered will now be displayed in the table. The correct values can be arrived at iteratively by scanning and observing the margin size on the scanned image.

To set automatically, press <A> and the message “ Feed in Black Document “ will appear. This should be a dark blue or black A size document. Align it to the rightmost edge of the active scan area marked by a black line on the scanner top plate. Page Offset determination will now proceed automatically. The determined offsets will appear dynamically in the table as they are calculated.
