Unwanted horizontal white lines or stripes appear
Problems with print quality, especially horizontal white lines in your document, may mean a nozzle on the print head is clogged or your ink cartridge is running out of ink.

Turn the printer off and unplug it. Then open the printer and carefully clean the rollers and platen with a soft, dry cloth.
