Hello EinkaufHL
Sorry, but this machine can NOT scan or copy A3!!!! Furthermore, it has only been available since this year, see top prices / price chart for this model.
In this brochure from Brother you can see very well which ink models of this series can print/copy/scan A3 and this also double-sided (duplex scan):
https://www.brother.eu/-...Tip, also look up Brother's top models, the X-series. As these have the much larger ink cartridges and can also print completely empty:
