1. Measure to alleviate problems of the center tray paper guide getting caught.

1.Model Name: SD-2060/ 2260/ 3062

2.General: There have been problems of the center tray paper guide becoming caught, causing

operation misses. As a measure to alleviate this problem, the measures described below
have been carried out.

3.Description: <1> There have been problems of the paper flow ribs of the upper paper guide and the

center paper guide upper becoming caught on the edge section of the fixed upper
paper guide. As a measure to alleviate this problem, a change has been carried out in
the ribs, reducing the height of the ribs to prevent obstruction. (Please refer to figure 1.)

<2> The addition of a spacer has been carried out to the back side of the paper feeding

paper guide lower. This change has been carried out as a measure to prevent the fixed
upper paper guide from warping and bending upwards. (Please refer to figure 2.)

<3> In accordance with the extending of the length of the ribs of the upper paper guide,

the mylar (Qty: 4) sheets have been discontinued. (Please refer to figure 3.)

<4> A change in the fixing screws (Qty: 8) which secure the fulcrum plate on the moving

side and the opening and closing plate on the moving side of the upper paper guide
has been carried out. This change has been carried out as a measure to improve
productivity. (Please refer to figure 1.)

Note: When carrying out replacement operations of the upper paper guide described in

above, replacement operations should also be carried out simultaneously on the
screws described in above.
