20130206061 | GLOSS PROCESSING APPARATUS - A sheet of paper is set on a paper-supplying portion of a top surface gloss processing apparatus while its top surface is faced upward. A gloss level sensor measures gloss level of the top surface of the sheet of paper. Data of this measurement is compared with a previously set threshold value. Based on this comparison, it is determined whether or not the gloss processing has been performed on the top surface thereof. When determining that the gloss processing has been already performed, a warning message such that the gloss processing has been already performed on the top surface of the sheet, of paper is displayed on a screen. On the other hand, when determining that the gloss processing has not performed, the top surface gloss processing apparatus performs the gloss processing on the top surface thereof. | 08-15-2013 |
20130206064 | GLOSS PROCESSING APPARATUS - A sheet of paper is set on a paper-supplying portion of a back surface gloss processing apparatus while its top surface is faced upward. A gloss level sensor measures a gloss level of a back surface of the sheet of paper. Data of this measurement is compared with a previously set threshold value. When this measurement result does not exceed the threshold value, it is determined that the gloss processing has not been performed on the back surface thereof. It is then determined whether or not the presently set operation mode is a top surface gloss processing mode. When determining that the present operation mode is not the top surface gloss processing mode, the operation mode is automatically changed from a presently set back surface gloss processing mode to the top surface gloss processing mode. | 08-15-2013 |
20140140710 | IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD - An image forming apparatus receives setting of an object to be adjusted, on an adjustment object selection screen when selecting an adjustment mode. After the object to be adjusted is set, camera(s) photograph(s) the object to be adjusted so that the image forming apparatus obtains photographed data of current object to be adjusted. Next, the apparatus searches photographed data of the object to be adjusted in the ideal state thereof from the database. Name of the object to be adjusted and related information in the photographed data agree with those of the photographed data of current object to be adjusted. The higher ranked related information is preferentially searched and it is determined whether or not pieces of the higher ranked related information thus preferentially searched agree with each other. | 05-22-2014 |
20150063848 | IMAGE FORMING SYSTEM AND CONTROL METHOD FOR THE SAME - A serial tandem image forming system is described which is capable of inhibiting both the degradation of image quality and the reduction of the productivity. This system consists mainly of the control units of upstream and downstream apparatuses. When a preceding sheet differs from the subsequent sheet in sheet type, a control unit for controlling the image forming system has the subsequent sheet stand by at a paper stop roller of the upstream apparatus, and performs the operation of switching the operating states of the upstream and downstream apparatuses in accordance with the sheet type of the subsequent sheet. Also, the control unit predicts the timing of finishing the switching of the operating state, and then re-starts the conveyance of the subsequent sheet, in advance of finishing the switching of the operating state, by controlling the paper stop roller on the basis of the predicted finishing timing. | 03-05-2015 |
