Cause
Color displacement occurred due to displacement of patch image to be formed at the time of color
displacement correction.
[Reference] Color displacement may also occur because of changes in outside air temperature/ temperature
increase inside machine/ machine relocation.
Field Remedy
Perform the following steps on the premise that the previous measure against mottled blank on image when
using papers of rough surface (reducing the thickness of ITB/increasing ITB tension/decreasing pressure of
the primary transfer roller) were taken and the system software was upgraded to Ver.70.09 (DCON
Ver.66.05) or later.
