Abstract: Data concerning misalignment of beams is measured and held in an optical scanning apparatus before the optical scanning apparatus is incorporated in an image forming apparatus. The optical scanning apparatus includes a light source for emitting multiple beams, an optical lens for converting the multiple beams to parallel lights and a rotating polygon mirror for rotary-deflecting the multiple beams. Furthermore, the measurement apparatus measures main scanning direction misalignment among the multiple beams on a photosensitive member provided for the image forming apparatus, which has been determined by detecting the multiple beams from the rotating polygon mirror (and an f? lens). The optical scanning apparatus includes a holding unit for holding the data concerning misalignment. The image forming apparatus in which the optical scanning apparatus is incorporated corrects the misalignment with the use of the data concerning misalignment inputted directly or indirectly from the holding unit.

Abstract: There is a problem of making it possible to set up a driver with a simple operation when a driver for a peripheral device on the network is not installed. When a driver setup instruction is given, an instruction is sent to the specified PC to perform an operation to set up the driver specified by the user, and the information processing unit performs the operation to set up the driver based on the instruction. For example, when the peripheral device is a printer, the information processing unit determines whether or not the setup operation has been completed normally, and if the driver has been correctly installed, test printing is executed.

Abstract: The measured density value of a printer at the time is compared with the density measured value at the time of adjusting a copy-forgery-inhibited pattern density, and the fluctuation amount of the output density of the printer from the copy-forgery-inhibited pattern density adjustment time until the time is calculated. It is judged whether the calculated density fluctuation amount exceeds a density region (the threshold of density fluctuation amount) which becomes effective as the copy-forgery-inhibited pattern image. When the density fluctuation amount exceeds the threshold of the density fluctuation amount, the user is notified that the density of the copy-forgery-inhibited pattern image may have inappropriate density as the copy-forgery-inhibited pattern image by the density fluctuation. Thereby, the user can check whether the present copy-forgery-inhibited pattern image is appropriate.
