Solid Printer has deserved its 4 stars

I have the printer now for 4 months with me in action. And am satisfied with the quality of prints. Scanning works very well only the option to create searchable PDF file was a little hidden, but as the pressure can not help it that the programmer of the software hidden.
Negative I can only think of that I can not turn off unnecessary functions. I need no cloud print (Google & Epson) & FAX functionality and would like to completely switch off but this is not provided in the printer's firmware.
If Tray 1 has run out of paper says my printer always proud you have no paper in tray 1 and a paper jam. First message is true, second not

What leads to the devaluation on 3 star:
This printer has a web interface where I can perform actions follow:
- I can configure the aforementioned cloud service
- Initiate a firmware update via the Internet
Miss -the printer's DNS & Proxy Server
Unfortunately, I can this frontend unfortunately miss no password, so each located in my LAN can configure this printer.
