Abstract

An electrophotographic printing control apparatus serves for transferring an image via an electrically biasable ITM drum to a conductive substrate. The electrically biasable ITM drum is in contact with the conductive substrate over a contact period during which the image is transferred to the conductive substrate. The printing control apparatus includes a bias unit which provides electrical bias to the ITM drum and with short circuit protection, and a bias switching unit controllable to cut bias from the bias unit to the ITM drum during the contact period such that the ITM drum is unbiased when in contact with the conductive substrate.
