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 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 an ink pack.
• 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.
