<div dir="auto">I think also depending on what software you use to scan makes a big difference some software has the ability to process the image according to a defined preset or even auto mode.

I don't believe so. Most scanners can perform auto calibration with <br>
reference to hidden black and white strips inside the case.<br>
For a lot of these scanners that use scanner-on-a-chip designs, that <br>
process has to be performed by the driver code and I don't think that <br>
has been written for this scanner as yet.<br>
