1. Take the fuser out of the printer. Show me how.
2. Check the fuser sleeve.

   If cracks or tears are present on the fuser sleeve, the fuser is damaged. To replace it with a new fuser, purchase a fuser kit. Then install the new fuser kit. Show me how.
   Otherwise, if the fuser is not damaged, reinsert the fuser into the printer. Show me how.
