  The present invention relates to a consumables usability determination device using a wireless tag capable of appropriately determining whether or not consumables such as ink and toner used in an image forming apparatus such as a printer, a copy, and a facsimile can be used. The present invention relates to an image forming apparatus using.

  Conventionally, a method has been devised for managing consumables such as ink and toner used in printers, copies, facsimiles and the like.

There exists patent document 1 as a prior art.
JP 2002-331686 A

  In Patent Document 1, it is determined whether the consumable is a genuine product or a recommended product. If the consumable product is not a genuine product or a recommended product, a warning is issued before printing.

  However, this conventional technique alone cannot solve the following problems. In other words, in offices where various types of printers, copiers, facsimiles, and multifunction devices are installed, it is cumbersome to manage consumables for each model. In many cases, it is difficult to determine which consumables are of which model.

  If all the consumables are genuine or recommended products and consumables of multiple models are mixed, the conventional technology only determines whether it is a genuine product or a recommended product. Cannot be determined. In order to search for consumables, it is necessary for the user himself / herself to make a judgment by checking the model number of the corresponding consumable by looking at the user manual of the manufacturer. It is also conceivable that the user manual is not near the device for setting consumables.

  Also, since there were consumables near the corresponding model, it is quite possible that the consumables are of a different model when unpacked and set.

  In addition, I see a picture of a packing box to replace consumables, but it is difficult to understand unless I am used to it. In addition, although guidance information indicating a procedure for exchanging consumables with a moving image or the like is prepared as a function in the apparatus, the user may not know to operate the function.

  In such a case, it is required to be able to determine whether or not an unpacked consumable is a consumable suitable for the model by a simple operation of the corresponding model. If the consumables brought by relying on the model number can be determined before unpacking, they will not be unpacked by mistake. Since consumables dislike moisture, the unpacked and unpacked items have different storage periods. If unpacked and stored, the desired performance may not be achieved.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and a consumable use availability determination device using a wireless tag that enables determination of conformity of a consumable without being unpacked and an image forming apparatus using the same.
