20080316541 | IMAGE FORMING APPARATUS, CONTROL METHOD THEREFOR, AND OPERATION APPARATUS OF EQUIPMENT - An image forming apparatus having improved installability and operability. The image forming apparatus has an operation unit thereof disposed on an arm extending from the apparatus and pivotable around a support member in substantially the horizontal direction, and has sensors for detecting the pivot position of the operation unit. An initial-screen setting screen determined based on the pivot position of the operation unit detected by the sensors is displayed on the operation unit. | 12-25-2008 |
20080317525 | BELT FEEDING DEVICE AND IMAGE HEATING DEVICE - A belt feeding apparatus includes an endless belt and a supporting member for rotatably supporting the belt. The belt feeding apparatus further includes a setting member for setting, when the belt is deviated from a widthwisely normal zone, an inclination angle of the supporting member to a return angle to return the belt toward the normal zone. The setting member also sets, when a predetermined time elapses from the belt returning to the normal zone, the inclination angle of the supporting member to a balance angle to keep the belt in the zone. | 12-25-2008 |
20080317526 | BELT FEEDING DEVICE AND IMAGE HEATING DEVICE - A belt feeding apparatus includes an endless belt; a supporting member for rotatably supporting said belt; and setting means for setting, when said belt is deviated from a widthwisely normal zone, an inclination angle of said supporting member to a returning angle to return said belt toward the normal zone, and for setting, when said belt is in the normal zone, the inclination angle of said supporting member to a balance angle. | 12-25-2008 |
20090295071 | IMAGE FORMING APPARATUS - An image forming apparatus including: a informing portion that issues information; a storing portion that stores sheets; a sheet detecting portion that detects presence or absence of the sheets in the storing portion; a determination portion that determines a type of the sheets stored in the storing portion; and a control portion that causes the informing portion to issue a predetermined information in a case where the absence of the sheets is undetected by the sheet detecting portion and a change of the type of the sheets is determined by the determination portion. | 12-03-2009 |
20090302522 | SHEET FEEDING APPARATUS AND IMAGE FORMING APPARATUS - A sheet feeding apparatus | 12-10-2009 |
20100091350 | METHOD FOR CONTROLLING IMAGE FORMING APPARATUS - An image forming apparatus that previously rotates a polygonal mirror drive motor before starting a job and forms a latent image by using an optical scanning unit including the polygonal mirror drive motor is provided. The image forming apparatus includes a control unit configured to perform control such that, in the determination of the presence or absence of each of color toners before a previous rotation is started, if it is determined that any one of the color toners is absent, only the polygonal mirror drive motor corresponding to a black toner is previously rotated. | 04-15-2010 |
20100092193 | METHOD FOR CONTROLLING IMAGE FORMING APPARATUS - An image forming apparatus that previously rotates a polygonal mirror drive motor before starting a job and forms a latent image by using an optical scanning unit including the polygonal mirror drive motor is provided. The image forming apparatus includes a control unit configured to perform control such that, in the determination of the presence or absence of each of color toners before a previous rotation is started, if it is determined that any one of the color toners is absent, only the polygonal mirror drive motor corresponding to a black toner is previously rotated. | 04-15-2010 |
20100310265 | IMAGE FORMING APPARATUS - An image forming apparatus which makes it possible to resolve correction error of potential unevenness caused by insufficient mounting accuracy of an image carrier, in a relatively short time period without performing a conventional operation for removing the image carrier. The image forming apparatus includes a photosensitive drum, an exposure unit, an electrical potential sensor, a shading data ROM, and a CPU. Electrical potential data items associated with respective positions on the surface of the photosensitive drum are stored in the shading data ROM. The CPU corrects an exposure amount onto the photosensitive drum by the exposure unit, based on the electrical potential data read from the ROM, and based on the result of correction, adjusts timing for reading out the data. | 12-09-2010 |
