I have a Samsung laser all in one that has generally been a great, cost-efficient maching. It allows for manual duplexing by putting pages that have been printed on one side back in to be printed on the otherside. However, once the first side is printed the pages become very clingy to each other with static electricity and stick together when feeding through the printer, making the dupexing job very frustrating. Any body had similar experience and/or know of a fix? Thanks.
