How to Troubleshoot the GBC H420
To use the GBC H420 laminator, insert a paper document and wait for it to come out with sheets of plastic molded to both sides. Lamination provides documents protection from water damage, dirt and markings. A laminated surface can be marked on with a dry-erase marker and the markings can be erased with a damp or dry cloth. Many offices use laminating machines to protect documents.
