ABSTRACT:
The processor is designed to develop imaged film in sheet or roll form, using a leaderless system employing edge guiding of the film. In this design the exposed film is transported in such a manner that no physical contact is made with the image area by any part of the processor until the image has been fused onto the film. The toned and fused image is permanent and smudge proof.
The processor, as it is designed, has the capability of using different toners, adjusting film speed to meet toning and fusing requirements, changing fusing temperature depending on the toner at a given film speed, and adjusting the action of the air knife to improve its doctoring of the toned image prior to fusing. The processor is compact and lightweight, and the design gives due consideration to the health and safety of the operator.
An important feature is the toner tray which has multiple inlets for toner with a central discharge to protect the film that is being processed from scratching.
