摘要： The quantity of light of an optical sensor including a light emission portion and a light reception portion is adjusted through calculation before sheet detection is performed. In order to perform the light quantity adjustment, a voltage to be applied to the light emission portion of the optical sensor is obtained by performing calculation based on a relation between a voltage applied to the light emission portion before the adjustment and an output from the light reception portion before the adjustment. Then, it is judged whether the obtained voltage exists within a predetermined range and, if a positive result is obtained, the light quantity adjustment is ended. Further, a signal requesting the cleaning of the optical sensor is outputted in accordance with a value of the obtained voltage.

摘要： A sheet conveying apparatus permits keeping predetermined sheet intervals, even when sheet conveyance is temporarily discontinued and then resumed, after resumption of conveyance. The sheet conveying apparatus has a first roller which feeds sheets at predetermined sheet intervals, and a second roller which conveys a plurality of sheet fed from the first roller. After temporarily discontinuing conveyance of the plurality of sheets, conveyance of the plurality of sheets is resumed by use of the first roller and the second roller. The variation in the sheet interval caused when temporarily discontinuing sheet conveyance is corrected upon resumption of sheet conveyance.

摘要： A CPU for a motor driving apparatus of an image forming apparatus excites a predetermined phase winding among plural phases of a stepping motor for a predetermined time period. Thereafter, before a rotation of the motor is started, it is judged whether there is the possibility of deviating a positional relationship between a rotor and a stator of the motor from a positional relationship determined by the excitation of the predetermined phase winding for the predetermined time period, by an external force, on the basis of judgement whether a door is opened for jam treatment. If the possibility of deviation is judged, the predetermined phase winding among plural phases of the stepping motor is excited again for a predetermined time period.

摘要： There is provided an image forming system which is capable of performing image formation operations in an order identical or close to the order of reception of inputted print jobs even when some printers cannot output print jobs due to maintenance to thereby raise the operational efficiency. Scheduling is carried out to assign an inputted plurality of jobs to a plurality of image forming apparatuses. Respective maintenance times of the plurality of image forming apparatuses are monitored. When the result of monitoring is that the maintenance time of an image forming apparatus has been reached, scheduling is carried out to reassign unprocessed jobs out of the assigned jobs to image forming apparatuses other than the image forming apparatus for which the maintenance time has been reached. A CPU causes the other image forming apparatuses to perform image formation based on the reassigned unprocessed jobs.
