Hi:

This might refer to your scanner assy being locked. The scanner assy is the unit under the glass that scans your document prior to copying it. Look inside the cavity where you pick up your completed copies. Look at the upper left corner and see if there is a knob there. If there is, make sure it is in the completely unlocked position.
