Page 1 CAUTIONS KEEP HANDS AWAY FROM MECHANICAL DRIVE COMPONENTS WHEN THE COPIER IS WARM- ING UP. This is to avoid possible injury when the copier starts idling at the end of warm up. ALWAYS REINSTALL THE FUSING UNIT COVER AFTER SERVICING. This is to prevent the operator from accidentally touching the hot unit, or the fusing lamp terminal.
