Example implementations relate to determining a correction factor that converts a measured sensor distance to a calibrated sensor distance. The measured sensor distance may be based on an amount of substrate advancement through a web printing press between detecting a mark on the substrate at a first sensor and detecting the mark at a second sensor. The calibrated sensor distance may be the separation between the first sensor and the second sensor.

Measured sensor distance correction

Example implementations relate to determining a correction factor that converts a measured sensor distance () to a calibrated sensor distance (). The measured sensor distance may be based on an amount of substrate advancement through a web printing press () between detecting a mark (--N) on the substrate () at a first sensor () and detecting the mark at a second sensor (). The calibrated sensor distance () may be the separation between the first sensor and the second sensor.

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.
