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. 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.
