The Scanner Function
When Scanning Is Not Done As Expected
This section describes causes and remedies when scan results are not as expected.
Problem Cause Solution
The scanned image is dirty. The exposure glass, scanning
glass, exposure glass cover, or
ARDF is dirty.
Clean these parts. See p.113
“Maintaining Your Machine”.
The image is distorted or out
of position.
The original was moved dur-
ing scanning.
Do not move the original dur-
ing scanning.
The image is distorted or out
of position.
The original was not pressed
flat against the exposure glass.
Make sure that the original is
pressed flat against the expo-
sure glass.
The scanned image is upside
down.
The original was placed up-
side down.
Place the original in the cor-
rect orientation. See “Placing
Originals”, Printer/Scanner
Reference.
No image results from scanning.
The original was placed with
the front and back reversed.
When the original is placed
directly on the exposure glass,
the side to be scanned must
face down. When the original
is fed via the ARDF, the side to
be scanned must face up. See
“Placing Originals”, Print-
er/Scanner Reference.
The scanned image contains
white spaces.
If you scan originals using
functions other than the net-
work TWAIN scanner func-
tion, certain paper size and
resolution settings may pro-
duce scanned images that are
larger than the specified size
because of margins being add-
ed to the sides.
Scanning at a higher resolu-
tion may reduce the margins.
