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.
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.
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.
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.
