1. IMPROVEM ENT TO F A IL UR E O F T HE COPY PAPER FEEDING

2. IMPROVEMENT TO THE COPY DOUBLE FEEDING

1. Improvement to failure of the copy paper feeding

1.Model name: SD-2060

2.General: The picking up roller was the shaft integration type so the copy paper feeding failure

occurred when unlocking pressure welding of the roller was carried out slowly. We have changed types of the picking up roller to the one way type to reduce the load when the register roller started up and to improve torque margins of the paper feeding motor, and have aimed to improve paper feeding margins.

3.Description:

Picking up roller (Shaft integration)

After changes have been carried out, we supply the picking up shaft, the picking up roller and E5 as one package.
