Automatic Document Feeder (ADF)			Up to 50 pages Paper: 80 g/m²

Measured diagonally.

Measured when the machine is connected to the USB interface. Power consumption varies slightly depending on the usage environment or part wear.

When using ADF, single-sided printing and scanning, resolution: standard / document: ISO/IEC 24712 printed pattern.

Measured according to IEC 62301 Edition 2.0.

Even when the machine is turned off, it will automatically turn itself on periodically for print head maintenance, and then turn itself off.

Noise depends on printing conditions.

Measured in accordance with the method described in DE-UZ 205.

Print speed:

MFC-J3540DW/MFC-J3940DW/MFC-J6540DW/MFC-J6940DW
28 ipm (Mono) / 28 ipm (Colour)
MFC-J6955DW/MFC-J6957DW
30 ipm (Mono) / 30 ipm (Colour)

These print speeds were measured in accordance with ISO/IEC 24734.
