20090105968 | SYSTEM FOR PREVENTING TAMPERING WITH A SIGNAL CONDITIONER REMOTE FROM A HOST SYSTEM - A system for detecting tampering in a signal conditioner of electronics that determines a parameter from signals received from one or more sensors is provided. The system includes a host system that receives the parameter signals from the signal conditioner indicating properties of a material and supplies power to the signal conditioner. The signal conditioner is remote from and coupled to said host system. The signal conditioner generates the parameter signals. The host system is configured to periodically transmit a request for said authentication information to said signal conditioner, receive said authentication information from said signal conditioner in response to said request, compare said authentication information with initial authentication information, and detect said tampering condition in said signal conditioner if said authentication information is not equal to said initial authentication information. | 04-23-2009 |

20090060592 | CAMMING METHOD AND APPARATUS FOR CONTROLLING COLOR DEVELOPERS - A developer camming apparatus connected to a developer unit, including a slide, a motor, and an encoder, wherein the encoder determines a distance a developer unit is from the photoreceptor, wherein the encoder allows the developer unit to be sufficiently close to effect application of toner to the photoreceptor from the developer unit, but also does not allow the developer unit to contact the photoreceptor during a print job. | 03-05-2009 |

20090022521 | METHOD AND APPARATUS FOR CONTROLLING MULTIPLE COLOR DEVELOPERS USING A CAMMING MECHANISM - Aspects of this disclosure describe a multi-pass printer having a photoreceptor device mounted on an axis, a developer that is arranged adjacent to the photoreceptor device and is moving between a first portion and a second position, and a camming mechanism mounted on the axis that acts upon the developer to urge the developer between the firs and second positions. The camming mechanism can further include a camming disc that is mounted to rotate about the axis. The camming disc can also have an outer periphery edge having a first portion defined by a first radius and a second portion defined by a second radius. The camming mechanism can also have a developer roll spacing cam having an effective radius that maintains a spacing between the developer and the photoreceptor drum. | 01-22-2009 |
