Claim 0:
1. A sheet printer comprising:
an upstream sheet conveyor;
a downstream sheet conveyor adjacent to the upstream sheet conveyor in a transport direction of a sheet to define a transfer region, wherein the sheet is transferred between the upstream conveyor and the downstream conveyor; and
an air knife assembly positioned at the transfer region so as to overlap the transfer region for emitting an air current to control the landing of an edge of said sheet on the downstream conveyor, wherein the air knife assembly is configured for emitting an air curtain formed such that said air curtain and air currents resulting from said air curtain flow substantially perpendicular to said transport direction,
wherein the air knife assembly emits the air current towards the sheet, towards the upstream sheet conveyor and towards the downstream sheet conveyor,
wherein each of the upstream sheet conveyor and the downstream sheet conveyor include an endless transport belt, and
wherein the air knife assembly is configured for emitting the air curtain which extends substantially longitudinal in said transport direction.
