For example, it is quite able to automatically scan multiple documents grouped in A4 or A3 size. The result is very good. So all in all you can get, for example, a PDF document including all the different sheets scanned in one go, in front / back (Brother mode called DUPLEX) and this very quickly, which is not negligible when working in an office.
The ADF accepts up to 35 pages and feeds each sheet individually. As the size and weight of documents that Brother can handle, here is some information (in cm): LENGTH between 14.8 and 43.18 cm - WIDTH: between 14.8 and 29.7 cm - paper WEIGHT: 64 90 grams / m2. Personally, I regularly use the automatic scanning multiple grouped documents; loading and automatic scanning of several documents can be made with ease and speed.
At the office, the impression is very acceptable. Certainly, if I want to make prints / art prints, I use a different printer specially designed for art and photographic prints (quality photo printer typically has six to twelve different inks). However, for office use, the prints obtained with this Brother MFC-J6920CDW are very satisfactory.
