colors missing
' printhead did not start
printing correctly after refill.
D Solution - Slight color variation is normal,
particularly on glossy medias. The defect
should not normally be visible beyond
0.5-1.0 meter viewing distance. If a more
severe defect occurs, this usually indicates
that the printheads are dirty. Performing a
printhead recovery may fix this problem.
These types of problems may occur more
frequently when printing at low humidity
and temperature.
4 Missing single row of dots within 0.4
I of refill '
there is nozzle not functioning on the printhead.
The printer cannot hide nozzles within 0.4” of a
refill if you are using a type B refill.
5 Improving color variation seen at refill.
D Solution - If customer is printing on coated
paper, check that they have indeed loaded it
as Coated or Heavy Coated media. If not,
they should load the paper as the correct
type, or select Refill Type A in the front
panel menus (Device Setup / Refill Type
/ Type A).
6 Improving haze seen at refill.
D Solution - Haze is the result of an ink-media
interaction that is also dependent upon time,
humidity, and temperature. Printing in very
dry conditions will increase haze problems.
Refill Type B will usually give better haze
results than Type A ( a thin line instead of
1 cm band of haze). On some medias, Refill
Type C may reduce or eliminate haze
problems. The Refill Type can be selected by
the user through the front panel menus,
Device Setup / Refill Type / Default is
the normal setting, which chooses
automatically between Refill Types A, B or C
based upon Media type selection and Quality
level selection. The User’s Guide contains a
table with the default selections.
