1. Measure to alleviate problems of cracking of the exposure paper guide in the RDH.
1.Model Name: SD-4085
2.General: There were some problems of the fixing screws which secure the No. 1 exposure paper
guide and the No. 2 exposure paper guide the frame F and frame R in the exposure
frame unit in the RDH being too long, causing the paper guide to have a tendency to be
pulled, and resulting in damage to the paper guides. As a measure to alleviate this
problem, the measures described below have been carried out.
3.Description: The 8 fixing screws of the No. 1 exposure paper guide and the No. 2 exposure paper
guide have been changed to shorter screws.

No. 2 exposure paper guide (P/G [55]-20)
4.Action: From the start of 1997 June production.
(As a temporary measure, washers have been added to units produced in April and May.)
2. Measure to improve the paper feeding performance of the lower curl original
documents in the RDH.
