The main difference between the Brother MFC-L8390CDW and the MFC-L8390CDWQJ1 lies not in the technical specifications or the functions of the printer itself, but rather in the sales conditions and the promotions on sale.

- Technical specifications: Both models, MFC-L8390CDW and MFC-L8390CDWQJ1, have the same technical features, including print speed, paper capacity, security features and connectivity options.

- Promotions and offers: The MFC-L8390CDWQJ1 model may include special promotions or offers, such as cashback, that are not available for the model without the "QJ1" designation. This designation could indicate a specific sales campaign or sales programme.

Overall, it is the same product but with different sales conditions or promotions.

Is the power plug compatible with Switzerland? Or is it a UK plug?
If the price is 355 CHF, can I still claim the 100 CHF cashback from Brothers?
Thank you
