    摘要： An image forming apparatus includes a first roller pair including a first roller and a second roller, a first driving unit, a second roller pair, a second driving unit, an image forming unit, and a control unit configured to execute a first mode and a second mode. The second mode includes (1) a first processing, (2) a second processing, and (3) a third processing of controlling the first driving unit such that the rotational speed of the first roller pair becomes faster than the second rotational speed. The first mode includes (1) a fourth processing, (2) a fifth processing, and (3) a sixth processing of controlling the first driving unit such that the rotational speed of the first roller pair is decelerated from the first rotational speed to equal to or less than the second rotational speed.

    摘要： A printing system includes an offline estimation device that provides estimates for ink or toner use for a print job at a target printing device. The offline estimation device retrieves digital front end (DFE) version information, configuration setting information, and color printing resources from the target printing device. Using the DFE version information, the offline estimation device selects a raster image processor (RIP) from a plurality of RIPs of software versions available within the printing system. The offline estimation device configures the RIP with configuration settings of the configuration setting information. The color printing resources also are pushed to the RIP. The offline estimation device provides the ink or toner use estimate using the configured RIP.

    摘要： An image forming apparatus includes a first generation unit to determine a density in each of a plurality of regions of a first image formed by the forming unit, and generate first correction data for correcting a density of an image to be formed by the forming unit for each of the plurality of regions based on the density. The first correction unit corrects the density of the image to be formed by the forming unit for each of the plurality of regions based on the first correction data stored by the first storage unit. The second generation unit determines a density of a second image formed by the forming unit, and generate second correction data based on the density. The first determination unit determines an amount of unevenness in the main scanning direction of formation density by the forming unit based on the density determined by the second generation unit. The second determination unit determines that the first correction data is to be generated, based on the amount of unevenness determined by the first determination unit.

    摘要： A power detection device includes a first zero-crossing detector, a current detector, and a second zero-crossing detector. The first zero-crossing detector detects zero-crossing timing of an alternating voltage of power supplied from a commercial power supply and outputs a voltage zero-crossing signal. The current detector detects current of the power. The second zero-crossing detector detects zero-crossing timing of the current detected by the current detector and outputs a current zero-crossing signal. A power factor is obtained based on a phase difference between the voltage zero-crossing signal and the current zero-crossing signal, and active power is calculated based on a root-mean-square value of the alternating voltage, a root-mean-square value of the current, and the obtained power factor.
