    Abstract: A method to provide a highly intelligent, automated diagnostic system that identifies the need to replace specific parts to minimize machine downtime rather than require extensive service troubleshooting. In particular, a systematic, logical test analysis scheme to assess machine operation from a simple sensor system and to be able to pinpoint parts and components needing replacement is provided by a series of first level of tests by the control to monitor components for receiving a first level of data and by a series of second level of tests by the control to monitor components for receiving a second level of data. Each of the first level tests and first level data is capable of identifying a first level of part failure independent of any other test. Each of the second level tests and second level data is a combination of first level tests and first level data or a combination of a first level test and first level data and a third level test and third level data. The second level tests and second level data are capable of identifying second and third levels of part failure. Codes are stored and displayed to manifest specific part failures.

    Abstract: A vacuum evaporation container includinging a resistively heatable cylindrical crucible having at least one open end and having an axially aligned slot and a hollow cylindrical insert concentrically located within the cylindrical crucible, the insert having a slot aligned with the slot of the crucible, closed ends and an electrical conductivity less than the electrical conductivity of the electrically conductive cylindrical crucible. This vacuum evaporation container is employed in a vacuum deposition process.

    Abstract: In a xerographic development system in which an AC field is set up in a gap between a donor member and the photoreceptor to develop an electrostatic latent image, a series of tests are performed to ascertain that the width of the gap is within a suitable range. In test mode, various DC and AC biases associated with the field are systematically altered, and the reflectivities of resulting test images are read. Based on these reflectivity readings, it can be determined if the gap is too wide, such as to cause poor print quality, or too narrow, such as to cause arcing.
