Abstract: An image forming apparatus forms adjustment patterns having a predetermined edge interval on a recording medium, while moving a carriage mounted with recording heads that eject a liquid droplet on the recording medium and formed of a sub-scanning motor and the like in a main-scanning direction by a main-scanning motor. The image forming apparatus performs a positional deviation correction process in which the adjustment pattern formed on the recording medium is read by a reading sensor mounted on the recording heads, while moving the carriage in the main-scanning direction, to correct a positional deviation of a landing position of the liquid droplet ejected from the recording heads based on an ideal interval between the adjustment patterns and a read result of the reading sensor repeatedly at least twice.

Abstract: A method of adjusting the operation of printheads in a printing system with a moving sheet carrying device has been developed. The method includes identifying a first amount of sheet carrying device displacement and second amount of sheet carrying device displacement as the sheet carrying device carries a media sheet past first and second printheads, respectively, for imaging of a predetermined location of the media sheet. A time for operating the second printhead is adjusted based on a difference between the first sheet carrying device offset and the second sheet carrying device offset to provide color registration between ink drops of the first printhead and second printhead on the media sheet.

Abstract: Disclosed herein is a method of controlling a motor in an image reading apparatus. It may be possible to optimize the drive current of the motor for driving the movement of the scanning module by using information associated with, for example, the time it takes for the scanning module to return to a home or rest position after the scanning module is moved from the home position to a predetermined position. Such optimized drive current can result in improvements in the reading performance of an image by the image reading apparatus and reduction of power consumption.

Abstract: An image forming apparatus includes light sources, a light intensity controller, an optical writing unit, a controller, and an image forming unit. The light sources are switchable between activated and deactivated conditions according to supplied image data. The light intensity controller controls light intensity of the light sources. In the optical writing unit, light beams output from the light sources are deflected in a main scanning direction. The controller sets a given number of light sources to activated condition to write a latent image on an image bearing member according to an image forming line speed. The controller instructs the given number of light sources to emit light beams onto an image area on the image bearing member, and instructs all of the light sources to emit light beams at a blank area on the image bearing member to execute a light intensity control for all of the light sources.
