Note: ‘Group 4’ or ‘Group 3’ are compression methods which are optimised
for text and vector drawings. If you choose these compressions when scanning
a photo with many grayscales these compressions can result in a negative
compression: the file size increases instead of decreases. So use these
compressions with care.
PDF compression
Within the ‘PDF compression’ option, you can define the ‘Compression’ of the
file.
Compression can be (select with the arrow buttons):
■
Group 4
■
None
Note: Only choose ‘Group 4’ when you are sure you can use this compression
afterwards. Choose ‘None’ in any other case.
Resolution
The Océ TDS600 scan to file option allows you to scan at the following three
resolutions:
■
200 dots per inch (dpi)
■ 300 dpi
■ 400 dpi
The higher the resolution the better the image quality. Higher resolution also
leads to larger file sizes. The default value is 200 dpi.
Zoom

‘File mode’ to ‘On’ then the automatic ‘Zoom’ setting will result in ‘1:1’. You
can change this default setting into one of the following three settings:
Custom This option let’s you specify a custom zoom value. You can enter a
range from 25% through 400%. This value also shows the zoom value when
the option ‘Automatic’ is chosen.
