I have a Brother printer model MFC-6710DW that was connected to a Lenovo 901F10068US. The tower came with Windows 10 installed. I also have a Xerox 6204 Wide Format printer that was connected to this tower as well. One day both printers stop working with the Lenovo tower. Brother printer shows that its offline and the Xerox shows connection error. The rest of my towers in the office remain connected to both printers and have no issues. What do I need to do to fix this issue?
