White or Dark Lines in Printout

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.

• Adjust the print quality in the product software.

• 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.

• You may need to replace the ink cartridges.
