Human Factors
Aircraft was marshaled to lead line A and this brought engine directly under jet bridge. I had to raise bridge. If bridge had been any lower this would have been a very bad incident and myself and vendor would have been injured. I was unable to safely pull forward; I turned wheels to left limit to attempt to pull away from engine. I stopped and went down bridge to view engine/bridge proximity. I was now going to turn wheels to right limit to attempt to pull sideways along the fuselage to get to the door. The ramp agents realized they had parked on the wrong stop and they stopped me as they were going to push the aircraft back to the correct stop.
A gate agent operating a jet bridge reported the inbound aircraft nearly contacted the bridge because ramp personnel had used the wrong stop line.
