1. Model Name: 
  MX-DEX7 (Option for MX2301N Series/2600 Series/3100 Series) 
 
2. Symptom:
 
If a paper with many paper powders is used, the transport roller 2 and transport follow roller 
may get dirty with paper powders to decrease the carrying force of the rollers. This carrying 
force decrease may lead to a jam (DPFD2_S, etc.). 
 
3. Description:
 
To prevent a jam (DPFD2_S, etc.) from occurring, we have increased the load of the right door 
follow spring holding the transport follow roller from 14.7N to 23.5N and also the press-contact 
force of the transport roller 2 and transport follow roller to prevent the carrying force from 
decreasing. 
 
- Right door follow spring 
Before change : 14.7N load (silver) 
After change : 23.5N load (black)
