Refer to the following figure, turn the spanner of paper near end sensor to adjust the position of
paper near end sensor and weekend paper near end sensor. These two sensors both have five
levels, and the default level is as follows.
Figure appendix 3.1-10 Adjusting paper near end sensor with cantilever paper holder
The corresponding paper roll diameter of the 5 levels on both sensors is as follows:
Level 1: The detecting paper roll diameter of paper near end sensor is φ29.5mm, and the detecting
paper roll diameter of weekend paper near end sensor is φ40mm;

roll diameter of weekend paper near end sensor is 42mm;
Level 3: The detecting paper roll diameter of paper near end sensor is φ35.5mm, and the detecting
paper roll diameter of weekend paper near end sensor is 48.5mm;
Level 4: The detecting paper roll diameter of paper near end sensor is φ42mm, and the detecting paper
roll diameter of weekend paper near end sensor is 57mm;
Level 5: The detecting paper roll diameter of paper near end sensor is φ50mm, and the detecting paper
roll diameter of weekend paper near end sensor is 67mm.
