A manufacturing method of a printed material that stores machine-readable information, includes forming, on a base material, a first layer including a first code symbol that is machine-readable and represents first information, using a first coloring material, and forming, on the first layer, a second layer including a second code symbol that is machine-readable and represents second information, using a second coloring material that is different from the first coloring material and decolorable at a particular temperature, such that the first code symbol is at least partly covered by the second coloring material.

Manufacturing method of printed material

A server for controlling an image forming system according to an embodiment includes an interface that receives, from a user device, document data and instructions to print the document data. A storage section stores the document data. A controller determines a printing mode of the document data based on property information included in the document data. The controller selects for printing the document data, only one of a non-erasable image forming apparatus and an erasable image forming apparatus based on the determined printing mode. The controller controls a display device to display a screen for selecting an erasable printing mode designation if the printing mode is determined to be a non-erasable printing mode.

Image forming system and image forming method

An image forming apparatus according to an embodiment comprises a first image forming section configured to form an image on a recording medium with a non-erasable material, and a second image forming section configured to form an image on the recording medium with an erasable material. The image forming apparatus further comprises a control section configured to separate image data according to attributes of the image data into first image data to be printed on the recording medium in the first image forming section and second image data to be printed on the recording medium in the second image forming section.

Apparatus and method for forming an image on a recording medium using erasable material and non-erasable material

A decoloring device according to an embodiment includes a decoloring unit that erases a first image formed with erasable colorant on a first side of a sheet and a second image formed with erasable colorant on a second side of the sheet. A reading unit reads the first and second sides of the sheet and determines whether the first side and the second side are reusable. A single-side reusable paper tray stacks the sheet if the reading unit determines that only one of the first and second sides is reusable. A marking unit adds a mark to the one of the first and second sides that is determined to be not reusable when only one of the first and second sides is determined to be reusable.

Decoloring method and decoloring device

According to an embodiment, a decoloring device is disclosed. A decoloring unit decolors an image formed with decolorable colorant on a sheet. A reading unit reads a surface of the sheet to determine whether the surface of the sheet is reusable. When the surface of the sheet read by the reading unit is determined to be not reusable, a marking unit adds a mark to the read surface. A first tray receives the sheet on which a mark is added by the marking unit.

Apparatus that forms an image on a medium using a plurality of erasable materials and erasing apparatus

An image forming system according to an embodiment includes a data creation section that creates document data. A print instruction section sends instructions to print the document data. A printing mode determination section determines a printing mode of the document data based on property information of the document data. A selection section selects for printing the document data with one of a non-erasable image forming section and an erasable image forming section based on the determined printing mode.

The decoloring device further comprises a single-side reusable paper tray configured to stack the sheet if the reading unit determines that only one of the first and second sides is reusable, and a reversing unit configured to reverse the sheet and discharge the sheet to the single-side reusable paper tray so that the one of the first and second side determined to be reusable is stacked on the single-side reusable paper tray in a predetermined orientation.

An image forming system according to an embodiment comprises a data creation section configured to create document data, and a print instruction section configured to send instructions to print the document data. The image forming section further comprises a printing mode determination section configured to determine a printing mode of the document data based on property information of the document data, and a selection section configured to select for printing the document data with one of a non-erasable image forming section and an erasable image forming section based on the determined printing mode.

In a transport packet stream separating apparatus, a packet identification filter extracts transport packets having a predetermined packet identification from a stream of transport packets. Each of the extracted transport packets includes at least one section. A section filter unit determines whether a header portion of each of the extracted transport packets is coincident with a reference data, and receives the section of each of the extracted transport packets to output regardless of coincidence or discrepancy between the header portion of each of the extracted transport packets and the reference data. Also, the section filter unit generates a reset signal when it is determined that the header portion of each of the extracted transport packets is not coincident with the reference data. An interface unit receives the section data from the section filter unit, and stores the received section in a storage unit while updating a write address from a start address. Also, the interface unit resets the write address to the start address in response to the reset signal.
