Description: Under most circumstances, you'll want to make sure the manual feed selector is set to auto. When it's set to manual, the internal roller will sit flat on the ADF portion of the scanner and you will experience many double feed errors. The manual mode should only ever be used with the continuous feed option of the scanner.
Scanner Model: Panasonic KV-5055
Solution:
Simply toggle the indicated switch upwards toward the auto position and the rollers will cycle and reset.
