Maintaining Print Quality
Reducing Print Quality Degradation
from Ink Mist (Ink Spatter)
Under some printing conditions (such as low
temperature or when a static charge is likely), a
greater amount of ink mist (ink spatter during
printing) may be produced and adversely
affect the print quality. In these cases, you
may be able to alleviate the symptom by
lowering the rotation of the carriage fan.

Description
Whether the symptom can be alleviated or
not depends on the temperature and media
type. Be sure to check the print status as you
adjust the setting.
However, the purpose of the carriage fan
is to prevent ink buildup on the surface of
print heads. Lowering its rotation will lead
to more dot drop-outs. This means if you set
it to "MIDDLE, " "LOW, " or "OFF, " you should
perform normal cleaning more frequently.
The "PERIODIC CL. " setting (p. 17) is also
effective against dot drop-outs .
