If your printouts are faint or have gaps, try these
solutions:
Run a nozzle
check to see if any of the print head nozzles are clogged. Then
clean the print head, if necessary.
The ink
levels may be low. Visually check the ink levels.
Make sure
the paper type setting matches the type of paper you loaded.
Make sure
your paper is not damp, curled, old, or loaded incorrectly in your
product.
Align the print head.
Adjust the print quality in the product
software.
Clean the
paper path.
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.
If you cannot solve the problem using head cleaning,
you can print immediately from a Windows computer with a mixture of
color inks to create composite black. Select the Use a Mixture of Color Inks to Create Black
setting from Extended Settings on
the printer driver's Maintenance tab. You can print at Standard print quality when the Paper Type is Plain Paper / Bright White Paper,
Letterhead, or Envelope.
