Potential conflicts are determined using the adjusted constraints and a property of the print job.
A printing device includes an inspection system that uses variable intervals to inspect printed sheets for a print job. The variable interval sets the inspection points for the inspection process. Once a defect is detected on a printed sheet, the sheets in the paper path are cleared and separated into good and defective sets of sheets. The cleared sheets are sent to an output bin for further review. After addressing the defect, the last good sheet printed is determined and adjusted to resume printing operations.
A cushioning member according to the present disclosure includes a first member and a second member. The first member has a first recess shaped along a lower portion of an ink-filled ink pack. The second member has a second recess shaped along an upper portion of the ink pack. The ink pack is stored in a space formed by facing the first recess and the second recess. The ink pack is attached to an ink supply device in a state where it is placed on the first member.
A conveyance rollers pair includes a first roller and a second roller. The first roller has a uniform outer diameter and rotates around an axis. The second roller conveys a medium held between the first roller and the second roller while rotating around an axis. The second roller includes a shaft part, a plurality of columnar elastic members and a plurality of tube members. The shaft part extends in an axial direction and is supported rotatably around the axis. The elastic members are fixed to an outer circumferential surface of the shaft part at intervals in the axial direction. Each of the tube member has heat-shrinking property and water-repellency, adheres closely to an outer circumferential surface of the elastic member, and has both end portions which are protruded outward from both axial ends of the elastic member and have a diameter smaller than an outer diameter of the elastic member.

The driven roller includes a driven contact portion which comes into contact with the drive contact portion at a non-conveying position, and a plurality of protrusion portions which protrude outwardly in a radial direction. The plurality of protrusion portions are arranged in the groove portion at the non-conveying position. The drive contact portion is formed with a pair of guide portions which guide, to the groove portion, the protrusion portions of the driven roller moving from a conveying position to the non-conveying position.
A driving force transmission mechanism transmits a driving force fed from a driving source to a rotary member. The driving force transmission mechanism includes a driving gear, a drive-side coupling, an output-side coupling, and an urging member. The driving gear rotates by being fed with the driving force from the driving source, and has a hollow space along the rotation axis direction. The drive-side coupling is inserted in the hollow space in the driving gear, and rotates together with the driving gear. The output-side coupling is integral with the rotary member, and can couple with the drive-side coupling along the rotation axis direction. The urging member urges one of the drive-side coupling and the output-side coupling toward the other along the rotation axis direction.

The tank includes a connector and a channel member. The connector connects the circulation pipe and the tank so that the circulation pipe communicates with an inside of the tank. The channel member guides the cooling medium leaking from the connector to the storage pool.
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 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.
