The Paper Drawer says its Empty, and to Load Paper, but it is full?

Firstly, ensure paper is stacked correctly in the tray, and the paper guides are correctly positioned at the paper’s edge. Restack the paper as a per caution. Secondly, ensure the machine settings are the same as the paper in the drawer, as well as ensure the Computer settings are the same on the Copier. If using a Large Capacity Tray (two stacks of paper) ensure the left stack is to the far left and the right to the right.
