Info on a Multi-function (4 in 1) Colour Led Printer?

Hi I'm looking for a multi-function (4 in 1) colour LED printer for my small office with both Gigabit class Ethernet and 802.11ac Dual-Band and Dual-Radio wireless interfaces (the two interfaces will also have to work simultaneously), 2 GB RAM, more than acceptable print/scan/copy speed, two 250 sheet trays for printing and a 20 sheet tray for automatic scanning. Printing, copying, scanning and faxing must also have the automatic duplex function and a real resolution of at least 1200X1200DPI for printing/scanning/copying. The four functions of this printer will normally be used for documents and manuals with monochrome and colour images. In addition, this printer must be able to print/scan directly from/to USB sticks and memory cards and must work with Windows 7 SP1, Windows 10 v1903, MAC OS, Chrome OS Enterprise and directly with smartphones. The toners costs will have to be moderate. This network printer will be shared between five computers and will have to print/scan about 4000 pages per month. The budget is about 600-700 euro. Thanks Bye
