Step 6 Step 7 After the image is transferred, the media enters the fuser assembly where heat from the fuser and pressure from the pressure roller permanently bond the toner image to media. The paper delivery sensor (PS803) determines that the media has successfully moved out of the fusing area. The fuser assembly exit rollers deliver media to the paper output bin face down.

Step 6
After the image is transferred, the media enters
the fuser assembly where heat from the fuser
and pressure from the pressure roller
permanently bond the toner image to media. The
paper delivery sensor (PS803) determines that
the media has successfully moved out of the
fusing area.
Step 7
The fuser assembly exit rollers deliver media to
the paper output bin face down.
