| 20100321724 | MUTUALISTIC ENGINE CONTROLLER HAVING SENSOR COMMUNICATION - A printing device includes at least one printing engine that has many sensors (first sensors and second sensors) and at least one engine controller operatively connected to the printing engine. The engine controller uses software to control operations of the printing engine. Also, at least one non-volatile memory is operatively connected to the engine controller. The non-volatile memory stores values used by the engine controller to control operations of the printing engine. At least one adapter card is operatively connected to the non-volatile memory and to the first sensors and second sensors. The first sensors correspond to the design of the controller and are items designed as original equipment of the printing device. To the contrary, the second sensors correspond to the design of the adapter card and are items designed to be installed in the printing device after the printing device is in post production, customer service. The adapter card receives feedback from the first sensors and the second sensors and the adapter card reads and modifies incoming print jobs before the print jobs are delivered to the controller. | 12-23-2010 |
| 20100321725 | MUTUALISTIC ENGINE CONTROLLER HAVING CUSTOMER REPLACEABLE UNIT COMMUNICATION - A printing device includes at least one printing engine that comprises customer replaceable units. At least one engine controller is operatively connected to the printing engine, and the engine controller uses software to control operations of the printing engine. At least one non-volatile memory is operatively connected to the engine controller. The non-volatile memory stores values used by the engine controller to control operations of the printing engine. Additionally, at least one adapter card is operatively connected to the non-volatile memory and to the customer replaceable units. The customer replaceable units each comprise a memory unit. The adapter card reads incoming print jobs before the print jobs are delivered to the controller and the adapter card accumulates and stores statistics relating to print jobs within the memory unit of the customer replaceable units. The adapter card passes the incoming print jobs to the controller in an unaltered manner. | 12-23-2010 |
| 20100321726 | MUTUALISTIC ENGINE CONTROLLER COMMUNICATING WIHT PRINTER NON-VOLATILE MEMORY - A printing device includes at least one printing engine that has actuators and sensors. At least one engine controller is operatively connected to the printing engine, the engine controller uses software to control operations of the printing engine. At least one non-volatile memory is operatively connected to the engine controller. The non-volatile memory stores values used by the engine controller to control operations of the printing engine. Further, at least one adapter card is operatively connected to the non-volatile memory and to the actuators and sensors. The adapter card stores data and receives sensor feedback from the sensors. The adapter card uses the data and the sensor feedback to control the actuators by bypassing the engine controller when communicating with the actuators. The adapter card provides adapter card feedback to the non-volatile memory. | 12-23-2010 |
| 20110013959 | PROCESS FOR DEVELOPMENT OF CLEANING BLADE LUBRICATION STRIPES - According to aspects of the embodiments, there is provided an adaptive blade lubrication apparatus that includes a lubricant unit to place a lubrication stripe of lubricating material on a portion of a main surface; a cleaning blade that engages the main surface to remove excess toner thereon; and a controller configured to control the location of each lubrication stripe of lubricating material, wherein the controller places the lubricating material based on at least one of application frequency, blade lubrication state, blade engagement with the main surface. By varying the location of the lubrication stripe, the cleaning blade is better lubricated over the entire surface of the photoreceptor with the same or less lubricant than used in single location lubrication. Blade life and reliability are improved with more effective lubrication of the blade. | 01-20-2011 |
| 20110032306 | System for Reducing Metering Blade Wear in a Drum Maintenance Unit - A drum maintenance system for use in an imaging device includes a reservoir having a supply of release agent, and an applicator configured to receive release agent from the reservoir and to apply the release agent to an intermediate imaging surface of an imaging device moving in a process direction. A metering blade is positioned to meter the release agent on the intermediate imaging surface applied by the applicator. The metering blade has a longitudinal axis extending in a cross-process direction transverse to the process direction. A driver is operably coupled to the metering blade that is configured to translate the metering blade between a first position and a second position along the longitudinal axis. | 02-10-2011 |

| 20110268483 | WEB CLEANING SYSTEMS INCLUDING AN ELECTROSTATIC CLEANING BRUSH AND METHODS OF CLEANING PRINTED WEBS - Web cleaning systems, apparatuses useful in printing onto webs, and methods of cleaning webs are provided. An exemplary embodiment of the web cleaning systems includes a first web cleaning device having a rotatable first electrostatic cleaning brush for contacting a first surface of a moving web on which toner is disposed to remove un-fixed toner from the first surface; and a first brush cleaning device having a first cleaning member contacting the first electrostatic cleaning brush for removing toner from the first electrostatic cleaning brush. | 11-03-2011 |
| 20110286752 | APPARATUS AND METHOD FOR CLEANING A PHOTORECEPTOR IN A PRINTING APPARATUS - An apparatus and method that cleans a photoreceptor in a printing apparatus is disclosed. The method can include setting a voltage bias of an electrostatic cleaning brush in a printing apparatus to a first voltage bias. The method can include generating an image on media using a photoreceptor. The method can include cleaning the photoreceptor using the electrostatic cleaning brush operating at the first voltage bias. The method can include measuring operating conditions of the printing apparatus to determine an expected film accumulation rate on the photoreceptor. The method can include adjusting the voltage bias on the electrostatic cleaning brush to a second voltage bias based on the measured operating conditions. | 11-24-2011 |
