Those wipes help stop the build up of static electricity as the paper passes through the scanner throat. Some scanners also require daily wipe down with staticide wipes. If you don't have an isopropyl alcohol pad and need a quick fix then a slightly moist Kleenex tissue could be used. isopropyl alcohol pad) to remove any build-up of dust or dirt from it. We recommend cleaning the scanning lamp/lens assembly glass lens with the scanner vendor approved cleaning cloth (e.g. Take your time, do it thoroughly as explained below. DonвЂ™t give up after just 1 attempt to clean it off, please try several times.

I canвЂ™t stress enough that it can often take up to 5 attempts to fully clean off the built-up contaminanton the scanning lamp/lens glass surface,В soВ that itвЂ™s no longer causing unwanted lines on the scanned image. The scanner throat needs to be cleaned several times each day, and definitely before the start of each days scanning. In over 26 years of dealing with these types of issues, almost every issue is caused by dirt/dust/sticky tape building up on the scanner lamp/lens assemblies that the paper passes over inside the scanner throat. So the scattered light may accentuate one colour over others and that why we see the different coloured lines on the scanned pages. it allow slight to pass through it) and the contaminant causes the normally flat scanner lens glass surface to act more like a prism that scatter white light (like rain drops causing a rainbow). When scanning in colour mode the lines are different colours because the dirt/dust/sticky tape on the lamp/lens is often slightly transparent (i.e. Colour mode will often have different colour lines (red and blue seem to be quite common). Greyscale mode would have different shades of gray lines. Why are the lines on the images different colours? Well it depends whether you are scanning in B&W mode, greyscale mode or in colour mode. When you scan documents and you see a vertical line down the image that is not on the physical document, this is often caused by a contaminant like dirt or dust build up on the scanning lamp/lens assembly glass.Д¬ustomerвЂ™s often call and say they have black lines, grey lines, or different coloured lines on their scanned images.
