In the case of the Brother AIO's not so, mine can do an xsane controlled 
scan in single sheet load mode any size and location on an 11x17 glass. 
It also has a document feeder but xsane does not do duplex except as 
single images. In the case of my MFC-J6920DW, I don't believe the scan 
mechanism can turn the page over but once, which it does by default as 
the ADF works. But you can pick the page up from the output table, and 
without turning it over, place it back on the input ramp, as it actually 
scans the top of the sheet as its fed thru, becoming the bottom on the 
output table. Typical of the ADF's, the scanner head remains fixed but 
the paper is pulled across it.

One thing I might point out is that when driven from an ethernet port, 
there is always a 7 second lag between the access transmission to it, 
and its actually waking up to respond. This is caused by a bad checksum 
of the first 6 commands sent at 1 second intervals, but then the driver 
sends good stuff, ANAICT, till the end of that job.  Verified by 
wireshark watching the net traffic. Why the bad tcp checksum, I haven't 
a clue, but except for the wakeup delay, it just works. Presumably not a 
problem with a usb drive, but the location of the usb plug within the 
housing precludes access with a recommended maximum usb cable length of 
5 feet, unless you put a hub within 15 inches or so of the MFC, the rest 
of the cable is in the machine, useing up the majority of the cables max 
length in the circuitous path inside the machine.

Would I buy another Brother? Yes.
