  MX-2310U 

 
2. Description: 

If the cleaning bar is pushed into the rear of the frame with excessive force, this may cause the 
cleaning bar to become deformed making it protrude into the paper transport area. To prevent 
an "L4-12" 2nd transfer detachment error and to prevent the cleaning bar from being pushed 
past the designated position in the rear of the frame, a PTC cleaning bar stopper has been 
added to the PTC cleaning bar as provisional support. 
For permanent support, the profile of the PTC cleaning bar has been changed. 
 
- Provisional support (From initial production to mid-September 2010 production.) 

The PTC cleaning bar stopper is, as provisional support for production, is not prepared as a 
service part. 
 

 

 
- Permanent support (From mid-September 2010 production)
