Note 
Please wait for 30 minutes after installing a new Fusing Unit to allow 
the oil to circulate completely through to the Heat Roller.
 If you begin 
using a new Fusing Unit immediately, poor print quality may result. 
 
4. 
  Remove the Fusing Unit from the 
printer by holding the handles on 
both sides.
