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 are copying from the ADF, copy from the
scanner glass instead or use a higher quality setting.
When horizontal banding appears or the top or bottom
of the paper is smeared, load paper in the correct direction and
slide the edge guides to the edges of the paper.
When vertical banding appears or the paper is
smeared, clean the paper path.
You may need
to refill the ink. Visually check the ink levels.
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.
