Optimize the scan quality

Introduction
The printer can detect photos, rasters and fine lines on the original. This information is processed
in such a way that the digital result has a high scan quality. This means that in most cases you do
not need to adjust quality settings to get the best result.

Solution
You placed the originals in the wrong direction in the ADF or on
the glass plate.
Make sure the originals are placed correctly and scan the originals
again.
The [Original type] and [Size] settings that you selected do not cor-
respond with the orientation of the information on the originals.
Select the correct [Original type] and [Size] settings and scan the
originals again.
There is more than 1 explanation for this problem.
• Wrong orientation selected.
• Original feed direction confused with the orientation of the in-
formation on the original.
• The application you use does not process the TIFF/PDF file in
the right way.
Select the correct [Original type] and [Size] settings and scan the
originals again. If the problem remains, the application you use
can be the cause of the problem. Check the results in another ap-
plication.
This problem can occur when the size of the original and the selec-
ted size of the target scan are not the same. The problem can also
be caused by a (manual) change in the zoom factor.
Check the size of the [Original] and the [File] on the operator panel
and scan the originals again.
You can change the [Exposure] settings to influence the result.
