If you notice white or dark lines in your prints (also
called banding), try these solutions before you reprint:
Run a nozzle
check to see if any of the print head nozzles are clogged. Then
clean the print head, if necessary.
Make sure
the paper type setting matches the type of paper you loaded.
Make sure
you loaded the printable side of the paper correctly for your
product.
Turn off any
high speed settings in your product software.
Align the print head. If print quality does not
improve after aligning the print head, disable the bidirectional
(high speed) setting.
Adjust the print quality in the product
software.
If you continue to see horizontal or vertical bands
or streaks in your printouts after cleaning and aligning the print
head,you can finely tune the horizontal or vertical alignment in
the Maintenance menu.
If you continue to see horizontal bands or streaks
in your printouts after cleaning the print head and adjusting the
print quality, make print quality adjustments for each paper
type.
If you are copying from the ADF, copy from the
scanner glass instead or use a higher quality setting.
When vertical banding appears or the paper is
smeared, clean the paper path.
You may need
to refill the ink. Visually check the ink level.
If you have not used the product for a long time,
run the Power Cleaning utility.
Note: Power
Cleaning consumes a lot of ink, so run this utility only if you
cannot improve print quality by cleaning the print head.
