How do I clean the encoder strip on my Primera Printer?

The encoder strip is a clear plastic strip with small timing marks printed on it, which tell the printer where the print head is located along the horizontal print head path. If it becomes coated with ink, it can interrupt printing activity. It is normal for ink mist overspray to build up here over time. Use this method to safely clean the strip without damaging your printer.
