2. Measure to alleviate problems of black paper jams in the RDH section.
1.Model Name: SD-4085
2.General: There have been problems of jams occurring due to detection misses by the RDH photo
sensor (OPD 12 sensor). The misses were caused by the fact that the RDH photo
sensor was too far from the paper, and the detection misses were especially prone to
occur when using original documents which were very dark or black. As a measure to
alleviate this problem, a change in the distance of the sensor has been carried out.
