December 17, 2011
Subject Notes on Replacement of the ISU
FS-6030MFP, FS-6025MFP, FS-6025MFP/B, FS-C8025MFP,
Model
FS-C8020MFP

Topic
Abnormal images such as the samples below and an error at the U411 adjustment might appear when installing the
service parts ISU. In this case, please install the spacer to adjust the height after checking the image. The spacer
and the leaflet are now bundled in the service parts ISU.

Causes
Since the height and/or the warpage of the base to install the ISU slightly vary depending on the machine, the
optical axis might be shifted or interrupted by the reflector. If it is shifted to the optical guide plate, the LED light
might directly enter.
