Phenomenon caused by abnormal parts
Shortened life due to damage on the heat roller surface, degraded image gloss,
abnormal image, image dirt, improper fusing, paper jam, oil leakage, oil dirt
Greater banding, improper image (color shift, flow, deflection), toner dispersion
Trouble caused by improper adjustment
paper wrinkles
SPEC
Shortened life due to damage on the heat roller
surface, lower image gloss, image abnormality, image
dirt, improper fusing, paper jam, oil leakage, oil dirt
Phenomenon caused when the value is outside the specified range
Degraded accuracy of area separation
(degraded accuracy of filter process, black
character and black-line edge process)
Change in copy quality
due to change in setting
Fusing capability and
image gloss are changed.
Phenomenon caused when the
set value is changed
When the set value is decreased,
the oil supply is decreased. When
the set value is increased, the oil
supply is increased.
When the set value is increased,
the oil supply is decreased. When
the set value is decreased, the oil
supply is increased.
Perform the adjustment in case of improper fusing,
improper image gloss, paper jam, or paper wrinkles.
Phenomenon caused by oil filter problem
