Paper width: 2.75 inches (69.5 mm) or 3.00 inches (76.2 mm)
1) When the printer is shipped, the paper width is set for wide roll paper (3 inch or 76.2 mm
width).
2) To use narrow roll paper (2.73 inch or 69.5 mm width), hold up the roll paper guide and move
it to the left to insert into the hole (1) at the lower frame.
3) The gure below shows the proper guide position for narrow roll paper (2.73 inch or 69.5mm

1.5.1.3 Adjusting the Roll Paper Near End Sensing Position
The paper near end detector detects when the paper is almost gone by measuring the diameter of
the Roll paper.
If you want to change the amount of paper remaining when the printer stops printing, follow the
steps below to adjust the paper near end detector.
Note:If the inner diameter of the Roll paper core is more than 26mm (1.02 inch), the Roll
paper near end detector may not work properly.
1. Open the printer cover.
2 Determine the point on the Roll paper at which you want the near end detector to be triggered.
Then measure the distance A shown in the illustration.
Note:There may be some difference between the measured distance A and the actual
sensing position.
3. Find the corresponding adjustment position number from the table below.
Distance A Adjustment position number
4 mm (0.16") #1
6 mm (0.24") #2
8 mm (0.32") #3
11 mm (0.43") #4
19 mm (0.75") #5
26 mm (1.02") #6
Note:Above values are applicable when the inside diameter at the core of the Roll paper
is 10mm.
4. Loosen the detector screw with a coin or screwdriver.
5. Set the detector scale to the position you determined from the table by moving the detector
screw up or down. The numbers #1, #2, #3... are not marked on the detector scale.
6. Secure the detector screw; then close the printer cover.
