Hello!! The issue with my WC started when I sent a print from my PC, it took longer time processing the print yet nothing was printed. I looked at my xerox it showed communication error...restart, which I restarted the printer still cannot print nor copy. My observations: 1- I got 303.316.00 error code 2- All my toners are showing missing when they are properly installed. 3- When I open any of the doors or trays, I do not get any warning notifications on the display as well as beeps. Thanks for helping.
