Unprinted: Around Clear-toner Images
CMYK toner around clear toner images is not fixed and appears white.
Cause
This problem is caused by toner unevenness created when clear toner images are superposed for part
of CMYK toner images.
When paper [A] is transferred from the Intermediate transfer belt [B], some toner is not transferred due
to toner unevenness. This results in unprinted areas around clear toner images. This problem only
occurs in FCS or FCS Quality mode.
