Rotation error of gate

Corner Edge Folding

Changed Contents Parts Name Supplementary

To regulate the engagement amount of the armature and the sleeve of solenoid, a flange has been added to the sleeve. To prevent the spring inside the spring clutch falling between the arbors, the dimensions of the shaft have been changed. To improve the attraction force of the solenoid, the weight of the spring has been changed.

To prevent corner edge folding of paper (following condition), the shape has been changed. * When A4-R, LT-R, LG paper with a large curl is used for stacking in the ADU. Along with the change in shape of

K-SFT-GATE-2-80, the

shape of the guide has also been changed.

Note

If the spring of the current solenoid is exchanged

(3-1.SPE-SND-P/U-F30), the solenoid will have the same

performance as SND-P/U-F300-SP.

ADU stack error

In accordance with the shape change of

K-SFT-GATE-2-80, the

number of rollers has been changed from six to four.

When the smaller sheets ( A5-R, LT-R, etc.) are stacked, to prevent the trailing end of the paper remaining in the roller, a groove has been added to the roller. In order to stack curled paper smoothly in the ADU, the mylar has been added.

To prevent stacking error of thin sheets, the thickness of the black mylar has been changed.

To distinguish between the current and the new parts,

a 1 mm cut has been made in the corner of new black mylar.

[ADU kit]

The ADU kit is composed of the countermeasure parts for "rotation error of gate".
