I came in this morning and my Ricoh will not print. The machine seems up. The display is up, I can send a file to print, however it just sits there and says waiting to print. I have no errors. I tried rebooting the machine. I tried unplugging the machine and letting it sit. I tried going into service mode and printing a page from there and nothing prints. Every time I try to print, the file just sits in the queue as "waiting to print". Any idea on how to correct this?
