here is a new short video review to show you how new Manual Setting of margins in scanned PDF Documents works.
As you can see here it is very easy to setup margins of your PDF documents on that device. You can adjust either universal margins for entire document or, If you want, you can set margins for odd and even pages separately like on presented video. It is especially very usefull if you read some older scanned books or documents.
This tool works fine in M92 as well as in i62HD series
