8.10 PAPER END (Cont’d)
8.10.2 Paper End Error Detection
There are two ways to detect paper end error using the jump hole sensor and the media size.
Detection by Jump Hole Sensor
When the jump hole sensor detects no tag for 84mm (3.3”), a paper end error will be detected. Then the
printer will print an end mark on the tag and stop the print operation after cutting a valid tag.
Detection by Tag Size
The size of tag previously printed and the one currently being printed will be compared. When there is
+/- 5mm (0.2”) difference in size between those two tags, the printer will detect a paper end error and stop the
print operation after cutting a valid tag. If there is no valid tag, the print operation will be stopped by the
detection of an error.
Note that an end mark will not be printed on the tag if detecting an error related to tag size.
Note:
As for the tag (Center hole, Side hole, Edge (Notch)), there is 300mm (11.8”) or more in distance from the tag
end portion to the first hole, or the hole is masked with a label at the edge portion. Therefore, this detection
method will cause a paper end error.
