Comment 2 for bug 684017

Sorry for the late reply. The term 'frontend' scared me off :)

The frontend used is libsane-perl. i did a few runs with other frontends before posting this comment. Seems that this behaviour happens only with libsane-perl. Here's a short video of the scanner with libsane-perl: *i know it isn't much of an evidence*

For scanimage, on first try, upon cancelling, the scan head stops dead in its current position, light is off. Ran Simple Scan to return it to home position. However, subsequent tries are ok though still received some sort of pop-ups, each in separate windows.
- Operation cancelled
- Unknown message: Scanned page 1. (scanner status = 2)

For scanimage-perl, the scan head returns home, light is on.
- Unknown message: scanimage-perl: received signal INT
- Unknown message: scanimage-perl: sane_read: Error during device I/O
- Unknown message: Scanned page 1. (scanner status = 9)

For scanadf-perl, similar to scanimage-perl.
- Unknown message: scanadf-perl: stopping scanner...
- Unknown message: scanadf-perl: sane_read: Error during device I/O

For scanadf, the scan head returns home, light is off.
