TECHNICAL BULLETIN 
ENHANCEMENT FOR STRENGTH OF OPEN/SHUT LOW 
PAPER GUIDE, RECOVERY PERFORMANCE OF REVERSE 
GATE, DETECTION LEVEL OF TRANSFER SENSOR
 
 
1. Model Name:
 
MX-RB20(Option for MX-4140N/4141N/5140N/5141N) 
  MX-RB22(Option 
for 
MX-M365N/M465N/M565N, MX-M364N/M464N/M564N) 
 
2. Description:
 
Following modifications have been made to improve the strength of open/shut low paper   
 
 
guide at the open/shut low paper guide section and also to enhance the recovery   
 
 
performance of reverse gate and the detection level of transport sensor at the transport   
  section: 
 
 
    - The shape of open/shut low paper guide has been changed. 
 
 
    - Reverse gate return spring and actuator damper molt have been changed.

    - Strength improvement2 (PGIDM2751FCZ3 → PGIDM2751FCZ4) 
 
 
 
 
 
 
 
 
    - Strength improvement3 (PGIDM2751FCZ4 → PGIDM2751FCZ5) 
 
 
 
 
 
 
 
 
2. Enhancement for detection level of transport sensor (Extend the ribs of open/shut low PG at the   
 
    transfer sensor lever section higher by 1mm) (PGIDM2751FCZ2 → PGIDM2751FCZ3) 
 
 
 
 
 
 
 
 
3. Enhancement for recovery performance of reverse gate 
 
    - Increase of the load of reverse gate return spring: (Before change: 4.0N -> After change: 4.6N)
