Hii my name is Luna Falon i am from the technical team if you are facing a problem then you can visit our site. To change a Xerox printer from offline to online, first, check that the printer is connected to the network and powered on. Next, open the printer's control panel and select "Printer" or "Devices and Printers." From there, right-click on the Xerox printer and select "See what's printing." In the new window that opens, select "Printer" and uncheck the "Use Printer Offline" option. This should bring the printer back online and allow it to receive print jobs.
