Abstract
According to one embodiment, an image forming apparatus has a printing unit to print images on a sheet of paper from a paper storage unit and a conveying unit configured to convey sheets from the storage unit to the printing unit. A tag reader/writer communicates with a wireless tag on a sheet when the sheet is at a communication position on the conveyance path. A control unit determines whether a writing of data to a tag on a first sheet has succeeded, then controls the printing unit to print on the first sheet if the writing of data succeeded but not if the writing of data to the wireless tag failed. When writing of data to the wireless tag has failed, the control unit executes a tag data writing retry process on another sheet from the paper storage unit.
Claims20
An image forming apparatus, comprising:
- a paper storage unit;
- a printing unit configured to print images on a sheet of paper from the paper storage unit;
- a conveying unit configured to convey sheets one by one along a path from the paper storage unit to the printing unit;
- a tag reader/writer unit configured to communicate with a wireless tag on a sheet being conveyed by the conveying unit when the sheet is at a communication position on the path before the printing unit;
- and
- a control unit configured to:
- determine whether a writing of first data to a wireless tag on a first sheet has succeeded by controlling the tag reader/writer to read data from the wireless tag on the first sheet,
- control the printing unit to print an image on the first sheet when it is determined the writing of the first data to the wireless tag on the first sheet succeeded,
- control the printing unit not to print any image on the first sheet when it is determined the writing of the first data to the wireless tag on the first sheet failed, and
- after it is determined the writing of the first data to the wireless tag on the first sheet failed, execute a retry process by controlling the conveying unit to convey a second sheet from paper storage unit to the communication position on the path and the tag reader/writer to write the first data to a wireless tag on the second sheet.

A multifunction peripheral device, comprising:
- a paper storage unit;
- a printing unit configured to print images on a sheet of paper from the paper storage unit;
- a tag reader/writer unit configured to communicate with a wireless tag on a sheet at a communication position on a conveyance path before the printing unit;
- a first discharge location for sheets;
- a second discharge location for sheets;
- a conveying unit configured to convey sheets one by one from the paper storage unit to the printing unit and then to the first or second discharge location;
- and
- a control unit configured to:
