1. Measure carried out to alleviate problems of original document mis-counts in the
RDH unit.

1.Model Name: SD-4085

2.General: There was a problem of mis-counts sometimes occurring in the1-cycle detection arms

of the models listed above in cases when approximately 20 mm of the original
document upper curl is used. As a measure to alleviate this problem, a change has
been carried out in the method of assembly used for the 1-cycle detection unit. As a
result of this change the detection area has been improved. As a permanent measure a
change has been carried out in the alignment positioning holes of the gears.

3.Description: Marking of the gears has been carried out on the metal molds, to be used as alignment
positioning marks. The position of the marking hole(ø1) has been moved to the marking
