Subject: Vertical black streak on the left edge of the print-out
Model: FS-1028MFP/1128MFP
Phenomenon The vertical black streak may appear 1-2mm from the left edge of the print-out.
Cause Light from the laser scanner unit is reflected by the shutter spring at the drum unit.

seal drum frame B to prevent the light reflection from the shutter spring.
The seal drum frame B is a component part of the drum and is not available as a individual part.
