Description

本発明は、上記課題を解決するために、画像形成装置が、帯状の台紙に、所定の隙間を介して複数のラベルを剥離可能に貼付したロール紙と、印刷データを基に、現像剤像を形成する画像形成部と、前記画像形成部で形成した現像剤像を転写する中間転写体と、前記中間転写体に転写された現像剤像を前記ラベルに転写する転写部と、前記ロール紙を前記転写部の方向へ搬送する給紙ローラと、前記転写部の、前記ロール紙の搬送方向の上流側に配置され、前記ラベルの欠損を検出する欠損検出センサと、を備え、前記欠損検出センサにより前記ラベルの欠損を検出した場合は、当該欠損部への前記転写部による前記現像剤像の転写を防止する転写防止処置を実行することを特徴とする。 In order to solve the above-described problems, the present invention provides a roll paper in which an image forming apparatus has a plurality of labels releasably attached to a band-shaped mount via a predetermined gap, and a developer image based on print data. An image forming unit for forming a toner image, an intermediate transfer member for transferring the developer image formed in the image forming unit, a transfer unit for transferring the developer image transferred to the intermediate transfer member to the label, and the roll paper A paper feed roller that transports the label in the direction of the transfer unit, and a loss detection sensor that is disposed upstream of the transfer unit in the transport direction of the roll paper and detects a loss of the label. When a defect of the label is detected by a sensor, a transfer prevention process for preventing the transfer of the developer image by the transfer unit to the defective portion is performed.

Ｓ１８：上記ステップＳ１５で、今回の転写処理においてラベル欠損が発生することなく転写処理が終了したと判定した主制御部２は、記憶部４の表示情報格納エリアを確認し、表示情報格納エリアに表示情報が格納されていない場合は、再印刷結果の表示を不要と判定し、切断されたロール紙６の排出を確認したときに、今回の印刷処理を終了させ、ステップＳ１へ戻って印刷ジョブの受信待ち状態で待機する。 S18: The main control unit 2, which has determined in step S15 that the transfer process has been completed without label loss occurring in the current transfer process, checks the display information storage area of the storage unit 4 and stores the display information storage area in the display information storage area. If the display information is not stored, it is determined that the display of the reprint result is unnecessary, and when the discharge of the cut roll paper 6 is confirmed, the current print processing is terminated, and the process returns to step S1 to return to the print job. Wait in the reception waiting state for.

Claims

Roll paper in which a plurality of labels are releasably attached to a band-shaped mount via a predetermined gap,
An image forming unit that forms a developer image based on print data;
An intermediate transfer member that transfers the developer image formed in the image forming unit,
A transfer unit that transfers the developer image transferred to the intermediate transfer body to the label,
A paper feed roller for conveying the roll paper in the direction of the transfer unit;
A loss detection sensor that is disposed on the upstream side in the transfer direction of the roll paper of the transfer unit and detects a loss of the label;
An image forming apparatus, wherein when a loss of the label is detected by the loss detection sensor, a transfer prevention process for preventing the transfer of the developer image by the transfer unit to the defective portion is performed.

The image forming apparatus according to claim 1,
