Brother flatbed batch scan

Hello,

I have a question about batch scanning from flatbed with scanimage, using a Brother DCP-7040 scanner.
scanimage version = 1.0.24. Printer is USB 2.0 device using Brother linux drivers.

From the man page (openSUSE Leap) I used following parameters:

scanimage --batch=score-%d.pbm --batch-count=16 --batch-prompt -p -v --source=Flatbed --mode="Black & White" --resolution=600 -x 210 -y 297

After scanning first page correctly and waiting for 2nd page, I place 2nd page on the flatbed and press Enter.
Then I always get following message :
Scanning page 2
scanimage: sane_start: Document feeder out of documents

So it seems that after first scan, the command tries to scan from ADF instead of flatbed as requested.

Is it a known bug with Brother devices or issue with command... ?

For those interested, this is the complete output in terminal:
scanimage --batch=score-%d.pbm --batch-count=16 --batch-prompt -p -v --source=Flatbed --mode="Black & White" --resolution=600 -x 210 -y 297
scanimage: rounded value of br-x from 210 to 209.981
scanimage: rounded value of br-y from 297 to 296.973
Scanning 16 pages, incrementing by 1, numbering from 1
Place document no. 1 on the scanner.
Press <RETURN> to continue.
Press Ctrl + D to terminate.

Scanning page 1
scanimage: scanning image of size 4960x6874 pixels at 1 bits/pixel
scanimage: acquiring gray frame
scanimage: read 4261880 bytes in total
Scanned page 1. (scanner status = 5)
Place document no. 2 on the scanner.
Press <RETURN> to continue.
Press Ctrl + D to terminate.

Scanning page 2
scanimage: sane_start: Document feeder out of documents


TIA
Bart.
