WARNING! Disconnect the printer from its power source whenever performing any maintenance or installation procedure. The printer is equipped with safety interlock switches on most of its covers. The switches disable parts of the printer when the covers are opened. These areas present the risk of electric shock, burns, and injury from mechanical hazards. Any unauthorized removal of safety covers, manipulation of safety switches, and interference with the safety system is strictly prohibited. Such actions can cause personal injury and can damage the system. Also make sure that the operating and maintenance areas are not obstructed in any way. With any drive mechanism, loosely hanging items of clothing and jewelry, such as ties, belt ends, necklaces, bracelets, and rings, and unprotected hair can cause injury if caught in the mechanism.
