A color printing system manages ICC profiles by controlling ink use without performing the ICC profile creation operations. To obtain an ink limit for an ICC profile, a table associated with the ICC profile is parsed to determine the ink limit. The ink limit is decreased or increased. For an ink limit decrease, a color over the decreased ink limit is adjusted to meet the new ink limit. The ICC profile is updated accordingly. For an ink limit increase, the combination of primary colors are boosted by a percentage amount. Checks are made with regard to the volume-based ink limit and an quality check operation to accepted the boosted amount. The ICC profile is updated accordingly.

The control unit (100) switches a dedicated manual input mode in which only the manual input instruction is received by the reception unit and a speech inputtable mode in which the speech instruction and the manual input instruction are received by the reception unit, and switches into the dedicated manual input mode when an operation screen (SC3) for receiving an input of information for which an input through a speech instruction has been forbidden is displayed on a display unit (101) by a display control unit (SC2).
An image forming device (1) comprises: a motion sensor (21); a microphone (22); a reception part (103); and a control part (100). When the motion sensor (21) detects an approaching person while the image forming device (1) is in a power-saving state, the control part (100): sets the microphone (22) to be in a speech inputtable state; releases, from the power-saving state, an operation mechanism that is necessary for executing a function associated with a content indicated by a speech instruction received by the reception part (103), to be in a normal operating state; and maintains the power-saving state of an operation mechanism that is necessary for executing a function not associated with the content indicated by the speech instruction.
A spot color adjustment system allows an operator to adjust spot colors through the use of test charts printed at a printing device. A target color swatch is determined from a first spot color. A test chart is generated based on the target color swatch that includes a plurality of rings of color swatches centered on the target color swatch. Each ring of color swatches is positioned around the target color swatch at an adjustment value. The adjustment value for each ring of color swatches corresponds to a color change from the target color swatch. The system allows for determining a number of rings of color swatches depending on a selected paper size. The outer rings of a large number of rings of color include intermediary color swatches. A midpoint color is determined from a plurality of selected color swatches. The system provides color swatches showing gray component replacement.
An object of the present invention is to correct the deviation of a sheet in the width direction occurring on a conveyance path from a sheet correction mechanism (4) to a discharge tray. A sheet shift portion (41, 43, 44) moves a sheet in the width direction. A conveying position detecting portion (45, 46, 47) detects the position of the sheet in the width direction. A discharge position detecting portion (54, 8a) detects a discharge position of the sheet, in the width direction, discharged onto a discharge tray (33) in a sheet discharge portion (31). A control portion (8b) derives an amount of deviation between the discharge position and a discharge reference position based on a detection result of the discharge position detecting portion (54, 8a). Furthermore, the control portion (8b) corrects a conveying position of the sheet in a sheet conveying portion according to the amount of deviation.

An image forming apparatus includes an image carrying member, a charging device, an exposure device, a developing device, a control section, and a temperature detecting device. The developing device includes a developer carrying member having an outer circumferential surface on which a toner layer is formed, and a regulation blade that regulates a thickness of the toner layer. The control section executes speed reduction control to reduce a rotation speed of the developer carrying member at a time of warming-up. When a printing operation to be performed after the warming-up is intermittent printing and an interval of the intermittent printing is not less than a prescribed time or a temperature detected by the temperature detecting device is not more than a prescribed temperature, the control section reduces the rotation speed of the developer carrying member in the speed reduction control to a second speed lower than the first speed.

An image forming apparatus includes an image carrying member, a charging device, an exposure device, a developing device, and a control section. The developing device includes a development container for containing a non-magnetic one-component developer composed only of a toner, a developer carrying member having an outer circumferential surface on which a toner layer is formed, and a regulation blade that regulates a thickness of the toner layer. The control section executes speed reduction control to reduce a rotation speed of the developer carrying member at a time of warming-up before image formation to a first speed lower than a reference speed at a time of the image formation. In the speed reduction control, the control section raises the rotation speed of the developer carrying member at a first acceleration rate until the first speed is reached from a state where rotation of the developer carrying member is stopped.

An image forming apparatus is capable of correcting a lateral deviation and/or a skew of a sheet. A pair of conveying rollers convey the sheet to a transfer position of an image. An image sensor reads the sheet on an upstream side of the transfer position in a sheet conveying direction. A control device senses a foreign substance on a reading surface of the image sensor as well as calculate a lateral deviation amount and/or a skew amount of the sheet based on an output signal of the image sensor.
