摘要： An image forming apparatus has a calibration mode in which a calibration image is formed on a print medium to correct image forming conditions. The image forming apparatus detects print medium information to determine, on the basis of the print medium information, whether the print medium is a sheet recommended as a print medium for use in the calibration mode. The image forming apparatus sets calibration conditions corresponding to the determined recommended sheet. The image forming apparatus corrects the image forming conditions on the basis of the set calibration conditions.

摘要： The present invention provides an image forming apparatus that adjusts the amount of light of a light-emitting unit with high accuracy and suppresses an increase in control time that is required to adjust the amount of light, a scanning optical apparatus, and control methods thereof. To accomplish this, the image forming apparatus of the present invention derives a threshold current and a bias current of the light-emitting unit. Further, the image forming apparatus of the present invention supplies the bias current to the light-emitting unit when causing the light-emitting unit to emit light in an amount of light corresponding to the minimum density level, and supplies a current that is larger than the threshold current to the light-emitting unit when causing the light-emitting unit to emit light in an amount of light corresponding to a density level that is larger than that minimum density level.

摘要： A printing system includes a plurality of printing apparatuses connected to a network and at least one control apparatus for sending a print job to each of the printing apparatuses instructing each of the printing apparatuses to execute the print job. In this system, when a first printing apparatus is instructed to execute the print job, the control apparatus makes a substitute printing reservation for at least one second printing apparatus so that the second printing apparatus may execute the print job instead of the first printing apparatus. The second printing apparatus is set to a waiting state for waiting to execute the print job instead of the first printing apparatus.
