An image formation system includes: an image former that forms an image on a continuous sheet; a slack generator that is arranged upstream of the image former in a sheet conveyance direction and generates slack on the continuous sheet; and a sheet characteristic detector that is arranged upstream of the slack generator in the sheet conveyance direction and detects a sheet characteristic of the continuous sheet.

According to one embodiment, a temperature control apparatus supplies power to a heater to control temperature of a temperature control target. The temperature control apparatus includes a temperature estimation unit to estimate a temperature of a temperature control target based on electrical power supplied to the heater. The temperature control apparatus also includes control signal generation unit that calculates a duty value for the heater based on an estimated temperature from the temperature estimation unit, a detected temperature from a temperature sensor, and a target temperature for the temperature control target. A pulse signal for controlling the electrical power supplied to the heater is generated based on the calculated duty value.

An image forming apparatus includes a transfer belt, a forming unit, a detection unit, a correction unit, a drive system, a determination unit, and a notification unit. The forming unit forms an image-misregistration detection pattern of a plurality of colors on the belt. The correction unit corrects an image misregistration of an image of each color based on a detection result of the pattern. The determination unit detects a difference amount between a pattern interval of the pattern on the belt and a pattern interval serving as a reference value for each color and determines that an abnormality has occurred in a driving state of the drive system, in response to the difference amount equal to or greater than a threshold value. The notification unit notifies occurrence of the misregistration when the determination unit determines that the driving state is abnormal, based on the difference amount of any one color.

An image forming apparatus includes a developer bearing member, a frame having a storage member, and a first temperature detection unit. The storage member is for storing a developer for the developer bearing member to record an image on a recording material. The storage member includes an attachment part in which a supply container enclosing a developer is removably attachable to the attachment part. With reference to a recording material conveyance path having a center in a width direction of the recording material that is orthogonal to a recording material conveyance direction and in a case where an area on one side of the conveyance path center is a first area and the area on the other side of the conveyance path center is a second area, the attachment part is arranged in the first area and the first temperature detection unit is arranged in the second area.

An image forming apparatus includes a first duct unit, a first air blowing fan, a second duct unit, a filter, and a second air blowing fan. The first duct unit includes a power source substrate, a first intake portion, and a first exhaust portion. The first air blowing fan forms an airflow from the first intake portion to the first exhaust portion. The second duct unit includes a second intake portion to take air in from inside the image forming apparatus, and includes a second exhaust portion to exhaust the air taken in from the second intake portion to outside of the image forming apparatus. The filter is disposed between the second intake portion and the second exhaust portion in an airflow from the second intake portion to the second exhaust portion. The second air blowing fan forms the airflow from the second intake portion to the second exhaust portion.

A sheet feeding apparatus includes an apparatus body, a cover openably and closably supported between a first closed position and a first open position, a first supporting portion movable between a second closed position and a second open position, an interlocking portion configured to move the first supporting portion from the second closed position to the second open position in a case where the cover is opened from the first closed position to the first open position, a second supporting portion drawably supported by the first supporting portion, and a feed portion configured to feed the sheet supported by the first and second supporting portions. A moving angle of the first supporting portion in moving from the second closed position to the second open position is smaller than a moving angle of the cover in moving from the first closed position to the first open position.

A sheet conveying device includes a separation member, a second conveyance member, a third conveyance member, and a first drive control portion. The separation member separates a sheet in contact with a first conveyance member from another at a first position where the first conveyance member comes into contact with the sheet. The second and third conveyance members are respectively downstream of the first and second positions. The first drive control portion stops driving the first conveyance member (1) after the leading edge of the sheet reaches the second position and before the trailing edge of the sheet passes through the first position when the sheet length is not exceeding a specific distance based on a distance between the first and third positions and (2) after the leading edge reaches the third position and before the trailing edge passes through the first position when the length exceeds the specific distance.

Batch generating of links to documents in which named content is automatically discovered within documents is disclosed. A selection of a plurality of documents is received from a user. Then, a list of search terms each correlated to a hyperlink destination is generated from the received selection of the electronic documents. Each of the plurality of electronic documents is scanned for text strings that match search terms stored in a list. Without user intervention, activatable hyperlinks from the matched text strings in the plurality of electronic documents are generated. Activatable hyperlinks to the respective matched text strings in each of the plurality of electronic documents are appended.

In one example in accordance with the present disclosure, a print device is described. The print device includes multiple consumable components. Each consumable component includes a portion of a hardware-based identifier. At least one sensor of the print device reads multiple portions of the hardware-based identifier. A controller of the print device combines the multiple portions of the hardware-based identifier and verifies the hardware-based identifier to determine an authenticity of the multiple consumable components.

A position detector includes a reading device, a position reference member having a mark opposite the reading device, and circuitry. The circuitry controls the reading device to detect the contour of the processing target and the position of the image pattern on the processing target and the position of the mark and corrects a processing position for the processing target to offset distortion of the reading device.
