Support for JPEG and PNG output was added to scanimage in 1.0.25. So if you have that (and your distribution enabled it), you don't need either of the *Magick's. Note that there were some bugfixes to the JPEG and PNG support in 1.0.27.

That may depend on the Debian version and architecture you're using.
You can check the package dependencies with
dpkg-query -W -f '${Depends}\n' sane-utils
On my machine (Devuan ASCII, approximately Debian 9), I get
adduser, lsb-base (>= 3.0-6), update-inetd, debconf (>= 0.5) |
debconf-2.0, init-system-helpers (>= 1.18~), libavahi-client3 (>=
0.6.16), libavahi-common3 (>= 0.6.16), libc6 (>= 2.15), libieee1284-3,
libjpeg62-turbo (>= 1.3.1), libpng16-16 (>= 1.6.2-1), libsane (>=
1.0.24), libsystemd0, libusb-1.0-0 (>= 2:1.0.8)
So, as mentioned already in my previous reply, I can use JPEG and PNG
but not TIFF.
Hope this helps,

Your scanimage needs to be linked to JPEG, TIFF and PNG libraries. You can check with ldd $(which scanimage) On my machine I get $ ldd $(which scanimage) linux-vdso.so.1 (0x7fffa9f9a000) libsane.so.1 => /usr/lib/x86_64-linux-gnu/libsane.so.1 (0x7f11434ed000) libpng16.so.16 => /usr/lib/x86_64-linux-gnu/libpng16.so.16 (0x7f11432ba000) libjpeg.so.62 => /usr/lib/x86_64-linux-gnu/libjpeg.so.62 (0x7f114304f000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x7f1142cb) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x7f1142aac000) libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x7f1142892000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x7f114258e000) /lib64/ld-linux-x86-64.so.2 (0x7f1143902000) So I can scan directly to JPEG and PNG but not to TIFF. If you're compiling scanimage yourself from source, you need to have the development packages installed before you ./configure.
