- Detailed failure when the fusing unit is removed while the pressure is not released: 
 
 
 
 If the fusing unit is removed while the pressure is still on, the pressure-release drive gear  
on the fusing unit suddenly rotates in the direction of the pressure release when removed from 
the attachment with the drive gear on the main machine, so some tip of the tooth for the  
 
  
 
pressure-release gear on the fusing unit may get broken. (See the photos below.) 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The fusing pressure-release trouble code “L4-16” will appear if the fusing unit with the gear 
broken is mounted on the main machine and then the power is turned on.
