2. Preventing screw contact with the DV hopper unit during insertion.

1.Model Name: SF-2025/2030/2040

2.General: During insertion into the main unit, the DV hopper unit may

come into contact with the screw fastening the frame cover

1 -23

(P/G ). To prevent this, we have changed the shape
of the insertion opening for the screw as indicated to the right.
(As a temporary measure, the old frame cover may still be used with a flat screw.)

3.Action: From the first unit of June, 1996 production.
