Nevertheless, the resulting image may have extra margins or some clipping of the content in some situations when detection of the edge of the paper is not accurate, which may also happen when scanning plain paper if the glass plate is dirty. In order to avoid these undesired effects, follow these recommendations. 1. Carefully clean the scanner's glass plate and the original to be scanned with a cloth. Turn the original 90 degrees if possible and re-scan it afterwards. Remember to select Translucent as the paper type at the scanner if your original is translucent. 2. If the problem persists, calibrate your scanner, and re-scan your original again afterwards. 3. If the problem persists in the case of translucent paper, attach a sheet of white paper to the back of the original to be scanned. A copied or scanned image is very skewed Originals are often loaded into the scanner with some degree of skew. In order to correct for this unavoidable problem, the scanner has a built-in automatic de-skew algorithm, which measures the skew in the original and rotates the scanned image so that the result is perfectly straight. However, in some cases the de-skew algorithm may increase the skew rather than correcting it. In other cases, the skew is so bad that it cannot be automatically corrected. To load the original with minimum skew, grasp the original with the image facing up and your hands at left and right edges. You are recommended to avoid resting your hands or the original on the scanner's input tray. Push the original into the scanner insertion slot until you feel the whole top border of the original pressing against the scanner rubber rolls, which will load the original after a delay of 0.5 seconds. Now you can take your hands off the original. If you are not happy with the way the scanner has grabbed your original, you can touch the Eject icon and try again. The action of the automatic de-skew algorithm can be deactivated by touching the Settings icon , then Scan preferences or Copy preferences (you might want to deactivate it in one case but not in the other). You can also deactivate the automatic de-skew from the Settings button at every new scanner job. 144 Chapter 16 Troubleshooting copy and scan quality issues (only MFP)

A copied or scanned image is very skewed
Originals are often loaded into the scanner with some degree of skew. In order to correct for this
unavoidable problem, the scanner has a built-in automatic de-skew algorithm, which measures the skew
in the original and rotates the scanned image so that the result is perfectly straight.
However, in some cases the de-skew algorithm may increase the skew rather than correcting it. In other
cases, the skew is so bad that it cannot be automatically corrected.
To load the original with minimum skew, grasp the original with the image facing up and your hands at left
and right edges. You are recommended to avoid resting your hands or the original on the scanner's input
tray. Push the original into the scanner insertion slot until you feel the whole top border of the original
pressing against the scanner rubber rolls, which will load the original after a delay of 0.5 seconds. Now
you can take your hands off the original. If you are not happy with the way the scanner has grabbed your
original, you can touch the
Eject
icon
and try again.
The action of the automatic de-skew algorithm can be deactivated by touching the
Settings
icon
,
then
Scan preferences
or
Copy preferences
(you might want to deactivate it in one case but not in the
other). You can also deactivate the automatic de-skew from the
Settings
button at every new scanner
job.
