Figure appendix 3.1-14 Adjusting paper near end sensor with cantilever paper holder
The corresponding paper roll diameter of the 4 levels of paper near end sensor is as follows:
Level 1: The detecting paper roll diameter is φ28mm;
Level 2: The detecting paper roll diameter is φ32mm;
Level 3: The detecting paper roll diameter is φ40mm;
Level 4: The detecting paper roll diameter is φ51mm.
The minimum remaining paper detected by paper near end sensor is as follows (theoretical value):

Figure appendix 3.1-15 Paper roll
A: Paper roll core ID
B: Paper roll core OD
C: Paper roll diameter
Notes
：
The above value is achieved under the condition that the paper roll core ID is 10mm and the OD is
16mm;
The minimum detecting value of paper near end sensor in the above table is theoretical, and there
will be deviation in the real practice.
