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.
