If I zuklappe the scanner, it is thus also switched off. The external power supply is relatively small, so do not bother. The cables have a decent length. The USB 3.0 cable is included. In addition, a transparent pocket is to scan special format documents without damaging them.
If there is a paper jam, the scanner can be opened with a handle that this button is placed handily. Afterwards you will be prompted to reload the paper.
I became aware of this scanner through various articles on the Internet. At Amazon, there are these scanners with different prices, as each different software is included. This offer here was the right thing for my Apple, everything works and works. The shipment was done quickly and efficiently.
