Adjusting the Roll 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 five settings. The factory setting (#5) leaves the least paper on the
roll when the near-end sensor is triggered. If you want more paper on the roll when the sensor is
triggered, choose one of the other settings, using the procedure below.
Note:
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.
1. Open the paper roll cover, and remove the paper roll.
2. Loosen the adjusting screw with a coin, and carefully move the detecting lever down. At the
factory the lever is set at the highest position (#5). As you move the lever down through the
five positions, you increase the amount of paper left on the roll when the near-end sensor is
triggered.

3. When you have moved the lever where you want it, tighten the adjusting screw, and check
to be sure that the detecting lever moves freely.
4. Replace the paper roll.
