I am trying to do 2-sided copy using the Document Scanner
app via the top feeder of a Canon E4570 scanner-printer.
The picture below shows the app setting before clicking Scan
. The app is able to scan the top page of the paper but not the bottom page of the paper. How do I activate duplex scanning?
System and App Info:
- system: Linux 6.8.0-40-generic #40~22.04.3-Ubuntu
- canon firmware: 1.070
- document scanner: 42.0
