ABSTRACT:
An imagesetting system includes: an imagesetter for photographically recording an image onto media; a wet chemical processor, proximately positioned adjacent to the imagesetter, for receiving and processing the imaged media, and a light-tight control wedge box containing a test strip to be processed by the wet chemical processor, without physically separating the imagesetter and the processor, to indicate whether chemicals in the wet chemical processor are depleted below a level of effectiveness. The imagesetting system operates in a test mode to determine whether chemicals in the processor are depleted below the level of effectiveness. The test mode method includes the steps of: stopping the imagesetter from photographically recording an image onto the media and stopping the imagesetter from transferring media to the processor; installing the control wedge box into the imagesetting system without physically separating the imagesetter and processor; and running a sequence of operations to extract the test strip from the control wedge box and to transfer the test strip through the processor to determine whether chemicals within the processor are depleted below the level of effectiveness.
