We have a sharp AL1631

there is proberly an sensort that has not been reset or a smalll bit of paper still in copier start from the begining off the process and pull the paper tray out and check to see if the papaer is set properly in the tray then follow the path through the copier to teh drum section and check the sensor arms are all free to move then to the fuser (HOt Section) make sure there are no small pieces left inside the path of the paper open all doors and check they close properly.. if you have checked all this correctly the light shoul go out on reset and you will be fine if not there is sensor not moving freely and yuo need to check again..Good Luck A
