An auto-compensating mechanism lifter comprises an auto-compensating mechanism and a lifter for moving a sheet of print media from a media feed tray in a document feeding device for printer, multifunction device or similar device. In a preferred embodiment, the present invention provides a reference that includes a body and a surface of the body. The driving circuits may also mitigate or eliminate high voltage arcing within the driving circuit. Cryptographic keys needed to decrypt the encrypted communications are provided via the separate channel to the security processor prior to commencement of encrypted communications. The control device controls voltage from the voltage source to charge the first and second mold portions, and detects the voltage between the first and second mold portions.
