    摘要: An image forming apparatus comprises a conveyance section, a plurality of sensors, an image forming section, a conveyance control section and a control section. The conveyance section forms a conveyance path for conveying paper. The plurality of sensors outputs detection signals indicating the existence of the paper at a plurality of positions along the conveyance path. The image forming section forms images on the paper conveyed by the conveyance section. The conveyance control section controls the conveyance of the paper conveyed by the conveyance section based on the detection signals of the plurality of sensors. The control section determines, in a case in which the detection signal of any of the plurality of sensors is abnormal, whether it is due to sensor failure or paper conveyance abnormality, and sets to ignore the detection signal of the failed sensor and continue the processing if it is due to the sensor failure.

    摘要: A method and control system for controlling an installation (1) for gathering flexible individual products (10), in which installation a stream of collections (20), which are from supplied streams that each have one individual product type, can be formed and conveyed to further processing (3). Each collection (20) has a predetermined quantity of individual products (10). Faulty collections (20) containing a supply fault with regard to one or several individual products are not processed separately but are regarded as faultless collections (20) under certain conditions. Accordingly, faulty collections advantageously not conveyed to a fault corrective action until a quota of the faulty collections exceeds a predetermined reference limit.

    摘要: A method for alerting a user when the time has arrived to replace a media feed roller on a printing device, employs statistical analysis of data gathered relating to the number of pages between misfeeds associated with the media feed roller. It has been ascertained that the misfeed rate associated with media feed roller failure follows a characteristic pattern, which may be treated as a step function. That is to say that, beginning with a new media feed roller, the feed failure rate, which is usually measured in pages printed between misfeeds, remains relatively constant. However, as the time for replacement nears, the graph begins to plunge precipitously, as misfeeds begin to occur with increasing regularity. After the plunge, the misfeed rate continues to increase, but at a decreasing rate. Eventually, the feed failure rate reaches a value that represents a misfeed during every page feed. The optimum time for replacement is deemed to be shortly after the graph begins to plunge. However, because there is a certain degree of randomness to the feed failure phenomenon, it is necessary that notification of the need for replacement of the media feed roller be given based on accumulated data sufficient to make a statistically valid directive to the printer user. The preferred method for providing a roller replacement directive to the user is to begin tracking feed failures when a feed failure rate value falls within a predetermined replacement range for the first time. After a statistically significant number of subsequent misfeeds indicate that the misfeed rate average is within the fixed replacement range, the replacement directive may be issued.

    摘要: A base material processing apparatus includes a transport mechanism, a force detection part, a meandering prediction part, a processing part, and a controller. The transport mechanism transports an elongated strip-shaped base material in a longitudinal direction thereof along a transport path aimed by a plurality of rollers of the transport mechanism. The force detection part detects a force applied to a sensing roller in an axial direction of a rotation shaft thereof, the sensing roller being at least one of the plurality of rollers. The controller predicts the meandering state of the base material to output meandering prediction information, based on the force applied to the sensing roller in the axial direction of the rotation shaft thereof. The meandering prediction part corrects the widthwise position of the base material relative to the processing part, based on the meandering prediction information. Thus, the base material processing apparatus is capable of sensing the meandering state of the base material through the use of the existing rollers of the transport mechanism in the processing part, and is capable of correcting the widthwise position of the base material relative to the processing part.
