SB 2J5-007

Abnormal sound from the exit section

Creation Date: 10/01/2012

Model: FS-6950DN/6970DN

Phenomenon The FD unit frame (Guide vertical) may warp upward around the center, due to the heat from

the fuser section. Under this condition the frame may contact the exit roller and the abnormal

sound may occur.

Solution Production measure

The Bush exit (302J528061) has been added between the frame and the shaft of the exit
roller, to avoid direct contact between the shaft and the frame.

Field measure

The Bush exit B (302J528070) has been registered. Please note that this part can be installed
without removing the FD unit.

Check points after reassembling the FD unit

• Check if the Bush exit holds the shaft of the exit roller after tting the Bush exit to the FD unit.

• Check if the bushing (Bush FD) is tted to the roller (Roller FD up) at the left side, when viewing the FD unit
from the front. (The drive motor is at the right side)

• Check if there is a gap between the resin frame and the bushing (Bush FD). If this is the case a paper jam or
abnormal sound may occur.
