We are a well-established firm that has made its presence in the industry, by exporting and supplying Encoder Strip. It is a small plastic strip with tiny vertical black lines on it that the print carriage uses with an optical sensor to read it's speed & position within the printer. Without it, the carriage will typically slam to one side when the printer is powered on. The strip will need to be replaced. It runs through a small slot/opening in the carriage & attaches at each end to the printer frame inside. One side usually has a spring or a spring metal piece that applies tension to the strip. Encoder Strip is suitable for all kind of industrial printers.
