Abstract
A photoreceptive sheet within an imaging apparatus is repeatedly transportable through a transport path and capable of capturing and transferring images. In addition, the photoreceptive sheet is repeatedly transportable for capturing and transferring a number of images. A transport path of the photoreceptive sheet can be a transport loop having a loop distance which can be greater than the length of the photoreceptive sheet. Excess ink or toner can be removed from the photoreceptive sheet by directing the excess to the resulting gap between a first end and the second end of the photoreceptive sheet and into a container.
