<p>PURPOSE: To provide a single pass direct transfer color printer capable of conducting an accurate image registration and an image transfer. CONSTITUTION: An image registration is improved merely by synchronizing a position and/or a speed of a paper web P to light receivers 70 of tandem print engines 20, 30, 40 and 50. A web tension is generated by a frictional slip between the wet and a sequentially feeding vacuum conveying mechanism 120, and a contact between the web and the receiver 70 necessary to transfer a good image is effectively obtained by the tension. A normal force to be applied to the engines is increased by one arch-shaped protrusion surface sheet route. Thus, a contact surface area between the engine and the web is not only increased, but also a contact pressure is increased. To reduce a disturbance caused by a vibration, a web buckle B is provided between the mechanism 120 and a fusion bonding unit 145, and a print-out of a valid size is provided by a cutter 150.</p> |
