Scanner of Canon MP830 does not work at all

My canon MP830 does not work at all, I think the problem was due to the scanner’s problem. The scanner/light bulb always stays at the end of right side of the scanner. The “Click” sound comes out of the gears when turning on the printer each time.
When doing copy job, the scanner does not move at all but only makes nooise. Then the message appears at the LCD display: “Scanner not work properly” and ” Error Cole 5010″. Sometime other messages would come out, such as ” Scanner is not operating correctly”, “Release the scanner lock switch and turn the power off and back on”, “Document in ADF. Redo operation after checking document in ADF and pressing [OK]” and etc.
