A control device determines whether an abnormality occurs in an image formed on a paper sheet with reference to image forming information regarding image formation generated by an image forming device that provides an area to be cut in the paper sheet and forms an image in an image forming area and read image information generated according to reading by a reading device that reads the image formed on the paper sheet, and generates control information for controlling image formation of the image forming device, wherein in a case where an abnormality is detected in the image forming area, the control device generates control information for adjusting positions of the image forming area and the area to be cut to move the abnormality to the area to be cut and notifies the image forming device of the control information.

An ink jet recording apparatus includes a recording unit, a plurality of rollers, and a notice control unit. The recording unit records an image on a sheet by causing a carriage mounted with a recording head to scan. The plurality of rollers presses the sheet. The notice control unit controls an error notice. In a case an error occurs in the recording unit, the notice control unit controls the error notice based on a relative position of the sheet with respect to the plurality of rollers at a time of occurrence of the error.

In a method for operating an inkjet printing machine, a condition of an ink is determined. A sedimentation and/or agglomeration of a pigmented ink is determined by refractometry, i.e. the value of the refractive index of the ink is measured with a refractometer and compared with a stored value with computer assistance.

A print consumable may include a rotatable core, a roll of dispensable print substrate, and a radio-frequency identification (RFID) tag. The roll of the dispensable print substrate may be dispensably secured to the core. The RFID tag may be secured to the core and configured to rotate about a core axis. The RFID tag includes an RFID antenna coupled to an RFID chip. The RFID chip may include a print counter, a stock-keeping unit (SKU) code, and a consumable authentication code. A print system may include a housing, a holder to hold the print consumable, a print head, a transceiver, a trace antenna for reading an RFID tag of the print consumable, and a controller. The controller may be configured to receive a signal from the transceiver indicative of one or more of the print counter, the SKU code, and the consumable authentication code received from the RFID antenna.
