First Claim
1. A blanket fastening assembly for securing an image transfer blanket to an intermediate transfer member drum of an electrostatic printer, the fastening assembly comprises a resilient biasing arrangement adapted to be connected to an end of the blanket to act in use so as to resiliently tension the blanket, with at least one end portion of the blanket being held in use by a resiliently biasing clamping member which is adapted to move during the operational life of the drum so as to accommodate stretching of the blanket whilst maintaining tension in the blanket.

13. A printer comprising imaging apparatus adapted to generate an ink image to be transferred to a substrate, the imaging apparatus comprising a blanket-mounting drum around which an image transfer blanket is removably secured, the blanket being adapted to receive an ink image for subsequent transfer therefrom, wherein the blanket is secured to the blanket mounting drum by a blanket fastening assembly comprising a spring-biased connector which is adapted to be connected to an end of the blanket so as to tension the blanket circumferentially of the blanket mounting drum.

14. An image transfer blanket for a printer comprising an image transfer surface adapted to receive and release an ink image, an electrically biasing layer adapted to cause the blanket in use to have an electrical potential, a first end region and a second, spaced, end region, the blanket being adapted to be wrapped around a drum in use with the first and second end regions generally adjacent each other, wherein at least one of the end regions has at least one of:
-
(i) apertures adapted to locate around projections of the drum and to control the positioning of the blanket on the drum;
(ii) a blanket clamping strip attached to said end portion and adapted to be releasably engaged by blanket clamping strip fixing formations on the drum;
(iii) a blanket clamping strip attached to said end portion and adapted to be releasably engaged by blanket clamping strip fixing formations on the drum, and said strip having teeth which extend through the blanket to the electrically biasing layer and which are electrically conductively coupled to the electrically biasing layer.
