Abstract
An image forming apparatus includes an RFID tag reader, an image forming unit, and a processor. The RFID tag reader is configured to read information from an RFID tag on a sheet conveyed along a conveyance path. The image forming unit includes a developer carrier. The processor is configured to determine, based on information read from the RFID tag on the sheet, whether information written to the RFID is correct. The processor is configured to cause the sheet to be conveyed to the image forming unit, a developer image already formed on the developer carrier to be removed without printing of the developer image on the sheet, and then print an alternative toner image indicative of a tag writing error on the sheet using the developer carrier.
Claims20
An image forming apparatus, comprising:
- an image forming unit configured to print images on sheets on a conveyance path, the image forming unit including a developer carrier on which developer images corresponding to images to be printed on a sheet are formed before printing on the sheet;
- an RFID tag reader configured to read information from an RFID tag on the sheet conveyed along the conveyance path;
- and
- a processor configured to:
- determine, based on information read by the RFID tag reader, whether information written to the RFID tag is correct, and
- when the information written to the RFID tag is not correct, cause the sheet to be conveyed to the image forming unit, a developer image already formed on the developer carrier to be removed without printing of the developer image on the sheet, and then print an alternative image indicative of a tag writing error on the sheet using the developer carrier.
An image forming method, comprising:
- reading, with an RFID tag reader, an RFID tag on a sheet conveyed along a conveyance path;
- determining, based on information read by the RFID tag reader, whether information written to the RFID tag is correct;
- and
- when the information written to the RFID tag is incorrect, causing the sheet to be conveyed to an image forming unit, a developer image already formed on a developer carrier of the image forming unit to be removed, and then print an alternative image indicative of a tag writing error on the sheet using the developer carrier.
