Paper near end sensor
The near end sensor for paper
roll in the printer is now able to
have the printer work with paper
rolls of several bobbin sizes. Please
refer to the picture at right from
inside the paper roll compartment
that there are a fixing screw and a
sensor head in the wall. Slightly
release the fixing screw to adjust the position of sensor head. The
acceptable paper roll bobbin outer diameter is between 18 and

overall diameter between 21 and 23.6 mm unless for too light
bobbins. Remember, for smaller roll diameter, the sensor head
should go higher.

bobbin body between the inner and outer diameter of the paper
roll bobbin nor to go into the inner diameter of the paper roll
bobbin. It is also noticed that some market available paper roll has
