19 Waste toner packing

 

 
[Symptom] 
Image is soiled in paper feed direction (sub-scan direction)   
 
[Probable cause] 
The rear duct filter is packed with dust or toner and the machine internal temperature rises.   
As the result, waste toner in the belt cleaning unit melts and then hardens up, causing the belt 
cleaning failure to occur.    The belt is soiled with toner   

 

 
 
[Solution] 
Replace the duct filter located on the backside of main body.
