Adjusting the Paper Near End Detector
The paper near end detector detects when paper is almost gone by measuring the diameter of the paper roll. The detector has two settings.
Because of variations in paper roll cores, it is not possible for the detector to measure exactly the length of paper left on the roll when the detector is triggered. Of the two settings, the factory setting (lower) leaves the least amount of paper on the roll when the sensor is triggered. If you want more paper left, change the setting as described below.
Note:
The factory setting is based on a paper roll core with an outside diameter of 18mm and an inside diameter of 12mm. If you use a paper roll with a core with an outside diameter of more than 18mm, it is better to change to the upper setting, as described below.
1.Open the printer cover, and remove the paper roll.
2.Loosen the adjusting screw and move the tab up to the upper setting.
