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.
