This error occurs when the peeling sensor is not shaded within the specified time.
This error occurs when there is a print jam.
The following cases can cause this error even though the print is not jammed：

-Printing is shrunken.
(Past cases: The cable tie (INSULOK) of the rear assist roller was not cut at the time of delivery. The print roller was worn. Because the cut position was too far, the label was fed too far backward, causing the tip of the label to come off the print roller.)

-The label is warped upward and does not shade the optical axis of the peeling sensor.
(Past cases: The label was issued leaning to the left because the label was skewed too far to the left. The peeling sensor was not positioned correctly. The angle of the peeling sensor in the case of IP was incorrect. In this case, it is better to adjust the optical axis by adjusting the peeling sensor position instead of adjusting the label issuing state.)

-The optical axis of the peeling sensor is positioned too far forward.
The above problems occur for a combination of reasons. Since these problems occur only in linerless printers, it is better to keep the peeling sensor as close to the print roller as possible to avoid unnecessary problems. (Because there is no possibility that the label liner will sag and shade the peeling sensor)

-An error occurs when manual labeling (issuing labels with the front cover open) is performed.
If the label is forcibly pulled out from the label holder immediately after label cutting (before the final feed), the peeling sensor cannot detect the label and an error occurs.
