Chapter 2 Setup
Adjusting the Roll Paper Near-End Sensor
Below are two situations where a roll paper near-end sensor adjustment is required.
• To adjust the detection position to suit the diameter of the roll paper core used.
• To adjust the detection position of remaining amount of paper.
Follow the steps below to adjust the roll paper near-end sensor.
1
Open the roll paper cover, and remove the roll paper.
2
Loosen the adjustment screw fastening the sensor, and align the upper edge of the
positioning plate with the adjustment position.
3
Tighten the adjustment screw.
4
After adjustment, make sure that the detection lever operates smoothly.
• The roll paper near-end detection function can be used only when this product is installed
horizontally.
• Be sure to disable the near-end detection when the product is installed vertically or is wall-
mounted. Failure to do so may lead to erroneous detection.
• Since roll paper cores vary slightly in shape, depending on paper roll design and manufacturing
tolerances, it is impossible to detect the remaining paper exactly.
• Use roll paper with a core inner diameter of 12 mm {0.47"} and outer diameter of 18 mm {0.71"}
so that the near-end sensor can detect the remaining paper as accurately as possible.
• To use the near-end detection, it must be enabled using the memory switches. See "Software
Setting Mode" on page 53 for details about the making the memory switch settings.
