1. Measure to alleviate obstruction problems in the copy lamp unit caused by screws.
1.Model Name: AR-280/285/335
2.General: When full scanning operations were carried out in the copy lamp unit of model AR-405,
there was a possibility of obstruction caused by the fixing screws which secured the
glass retainer right. As a measure to alleviate this problem a change was carried out in
the fixing screws, and the 4 × 6 screws were changed to 4 × 4 screws. This action has
also been carried out on the models listed above. In addition, the same change has
also been carried out in the fixing screws which secure the glass retainer left.
This action has been carried out as a measure to establish uniformity in the
manufacturing process operations.
3.Action: From the 1st lot of 1999 January production.
