5. Troubleshooting When
Using the Scanner Function
This chapter describes likely causes of and possible solutions for scanner func-
tion problems. When using the DDST Unit, see “Troubleshooting When Using
the DDST Unit”.
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 during
scanning.
Do not move the original during
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 exposure
glass.
The scanned image is
upside down.
The original was placed upside
down.
Place the original in the correct
orientation. See “Original Orien-
tation”, Scanner Reference.
No image results from
scanning.
The original was placed with the
front and back reversed.
When the original is placed direct-
ly 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 “Original Orien-
tation”, Scanner Reference.
The scanned image
contains white spaces.
If you scan originals using func-
tions other than the network
TWAIN scanner function, certain
paper size and resolution settings
may produce scanned images
that are larger than the specified
size because of margins being
added to the sides.
Scanning at a higher resolution
may reduce the margins.
