MEASURE CARRIED OUT TO ALLEVIATE
PROBLEMS OF U3-20 TROUBLE.
1.Model Name: SF-2050/2052
2.General: There were problems of U3-20 trouble occurring during Chinese (SOCC) production,
when the power supply of the machine was turned ON, due to the 2/3 mirror becoming
attached to the cushion even if the 2/3 mirror fixing screw was disengaged. This was
caused by the fact that the affixing strength of the 2/3 mirror fixing screw was too
strong. As a measure to alleviate this problem, a change has been carried out in the
fixing screw. The new fixing screws are longer than the old ones, and this has enabled
a lesser force to be exerted on the 2/3 mirror in the direction of the paper delivery side.
3.Action: * (For machines bound for the Chinese market)
- Chinese (SOCC) production: From 1998 mid-December production.
(For machines bound for the Chinese market)
- Japanese domestic production: From 1998 mid-November production.
(For all machines bound for markets other than the Chinese market)
- Running change carried out from 1999 January production.
