Horizontal banding at regular intervals, text misalignment, or carriage positioning errors — the encoder strip is a thin, translucent plastic strip that spans the width of the carriage rail with fine dark markings that the carriage uses for precise positioning; when ink or dust accumulates on the strip, the optical sensor in the carriage cannot read positions accurately; locate the strip (it runs horizontally through the carriage area) and gently wipe it with a soft lint-free cloth dampened with distilled water; support the strip from behind while cleaning to avoid stretching or breaking it
