Subject Measure against C3100 ISU Home Position Error
Model FS-3040MFP, FS-3140MFP
Topic
If the 2-pin wire is pinched between the mounting bracket for the CONNECT R PWB (302J101050) and the ferrite
core and the ferrite core is pushed by the right cover, the wire coating may be damaged. Therefore, the following
changes were made.
In case that the 2-pin wire coat was damaged and causes ground fault, the F3 fuse on the CONNECT L PWB
(302LW94190) may be blown and C3100 error may appear. (C3100: ISU home position error)
Content of Changes
The wire protective sheet (No.1) was applied to the 2-pin wire, which is aligned to the CONT.BOX side in order to
protect the 2-pin wire coating.
