20090297174 | CUSTOMER PART REPLACEMENT FEATURE UTILIZING HIGH FREQUENCY SERVICE INTERVAL FAULT AND SIGNATURE ANALYSES - A diagnostic system made part of or for use with a document handling device in which a customer is guided toward performance of at least one comparison means in a diagnostic routine analysis. The comparison means is selected from a group comprising (1) a first comparison comparing a fused print media and an unfused print media for presence of a defect, (2) a second comparison comparing an output print media and at least one image on a screen for a type of defect, and (3) a third comparison comparing a low-charged print media and a no-charged print media for qualities of the defect. The customer enters a selection based on results of the first, the second, or the third comparisons. The diagnostic system can identify a part causing a defect in the print media based on results of the comparisons. | 12-03-2009 |
20100028040 | METHOD AND APPARATUS FOR AUTOMATIC COROTRON CLEANING IN AN IMAGE PRODUCTION DEVICE - A method and apparatus for automatic corotron cleaning in an image production device is disclosed. The method may include receiving a first dynamic current reading, the dynamic current being the current supplied to a photoreceptor of the image production device, determining if the first dynamic current reading exceeds a predetermined threshold, the predetermined threshold being a threshold set on the allowable variation in the dynamic current value, wherein if it is determined that the first dynamic current reading exceeds the predetermined threshold, sending a signal to a cleaning device to clean the corotron, determining that the corotron has been cleaned, receiving a second current reading, determining if the second dynamic current reading exceeds the predetermined threshold, wherein if it is determined that the second dynamic current reading exceeds the predetermined threshold, sending a signal to prompt a user to replace the corotron in the image production device. | 02-04-2010 |
20100034543 | DIAGNOSTIC SYSTEMS AND METHODS FOR PROVIDING DIAGNOSTIC INFORMATION DURING SERVICING OF AN IMAGE PROCESSING APPARATUS - A diagnostic system that provides a service technician with service information during servicing of an image processing apparatus includes at least one counter that is incremented during operation of the image processing apparatus, a pressure detecting unit that detects a pressure at a point in an air flow path on the condition that the at least one counter is reset to zero after initial servicing of the image processing apparatus, a determining unit that determines whether a difference between the detected pressure and a fault threshold pressure is less than a predetermined margin, and a display unit that displays a fault code indicating additional servicing of the image processing apparatus is recommended on the condition that the determining unit determines that the difference between the detected pressure and the predetermined threshold pressure is less than the predetermined margin. | 02-11-2010 |
20100046974 | Systems and methods for controlling cleaning devices in image forming apparatus - Systems and methods are provided for controlling cleaning devices in image forming apparatus electrostatic image forming apparatus. Such systems may include a charge receptor, movable in a process direction, defining a main surface. A toner application device applies toner to the charge receptor, and is configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor at a selected time. An influence of a pre-clean corotron on the charge receptor is modified, during the designated rotations of the charge receptor, while the portion of the surface on which the lubrication stripe is formed, or will be formed, is passing the pre-clean corotron. The lubrication stripe is delivered to a secondary cleaning device including a blade engaging with the photoreceptor surface to lubricate the blade. | 02-25-2010 |
20100046975 | SYSTEMS AND METHODS FOR CONTROLLING CLEANING DEVICES IN IMAGE FORMING APPARATUS - Systems and methods are provided for controlling cleaning devices in image forming apparatus electrostatic image forming apparatus. Such systems may include a charge receptor, movable in a process direction, defining a main surface. A toner application device applies toner to the charge receptor, and is configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor at a selected time. An influence of at least one corotron on the charge receptor is modified, during the designated rotations of the charge receptor, while the portion of the surface on which the lubrication stripe is formed, or will be formed, is passing the at least one corotron. The lubrication stripe is delivered to a secondary cleaning device including a blade engaging with the photoreceptor surface to lubricate the blade. | 02-25-2010 |
20100046976 | SYSTEMS AND METHODS FOR CONTROLLING CLEANING DEVICES IN IMAGE FORMING APPARATUS - Systems and methods are provided for controlling cleaning devices in image forming apparatus electrostatic image forming apparatus. Such systems may include a charge receptor, movable in a process direction, defining a main surface. A toner application device applies toner to the charge receptor, and is configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor at a selected time. A primary cleaning device cleans the main surface of the charge receptor, and includes at least one biased member having an effective area associated with the main surface relative to motion of the charge receptor. A secondary cleaning device is configured to engage the main surface of the charge receptor downstream of the biased member, and a control system reverses a bias on the biased member during a time when a lubrication stripe is in the effective area of the biased member. | 02-25-2010 |
20100046997 | SYSTEMS AND METHODS FOR CONTROLLING CLEANING DEVICES IN IMAGE FORMING APPARATUS - Systems and methods are provided for controlling cleaning devices in image forming apparatus electrostatic image forming apparatus. Such systems may include a charge receptor, movable in a process direction, defining a main surface. A toner application device applies toner to the charge receptor, and is configured to place a lubrication stripe including the toner on a portion of the main surface of the charge receptor, the position of the lubrication stripe is controlled with respect to a position on the main surface of the charge receptor corresponding to a paper trail edge. The dimensions and density of the lubrication stripe may also be controlled. The lubrication stripe is delivered to a secondary cleaning device including a blade engaging with the photoreceptor surface to lubricate the blade. | 02-25-2010 |
