Description

前記メモリは、カートリッジ本体から取り外し可能であるか、または、分離可能であることが好ましい。 The memory is preferably removable or detachable from the cartridge body .

また、本発明の別の画像形成装置は、消耗品が収納されたカートリッジが交換可能に装填され、前記カートリッジ内に収納された消耗品によって記録紙にプリントを行う画像形成装置において、前記消耗品の推定使用量をメモリに書き込む情報書き込み手段と、前記メモリ内の情報を調べて前記推定使用量が所定値に達しているかどうかをチェックするチェック手段と、前記推定使用量が所定値に達した後も、前記カートリッジが装置本体から取り出されるまではプリント動作を許容するとともに、前記カートリッジが取り出された後、再度装置本体に装填されたときに、前記チェック手段によるチェックを行い、前記推定使用量が所定値に達している場合にはプリント動作を禁止する制御手段とが設けられている。なお、前記メモリは、カートリッジ本体から分離可能であることが好ましい。 Another image forming apparatus according to the present invention is an image forming apparatus in which a cartridge containing consumables is replaceably loaded, and printing is performed on a recording sheet by the consumables contained in the cartridge. Information writing means for writing the estimated amount of use in the memory, check means for checking whether the estimated amount of use has reached a predetermined value by examining the information in the memory, and the estimated amount of use reached the predetermined value After that, the printing operation is allowed until the cartridge is taken out of the apparatus main body, and after the cartridge is taken out, when the cartridge is loaded in the apparatus main body again, the check means checks and the estimated use amount And control means for inhibiting the printing operation when the predetermined value is reached. The memory is preferably separable from the cartridge body.
