To use the near-end sensor, set the remaining paper length to detect.
Follow the instructions given below.
(1) Open the rear cover.
(2) Use a ballpoint pen or a pointed object to pull the sensor up and move it to the appropriate position.
Check that the position is correct.
7. Adjusting the Near-End Sensor
Note:
1) The adjuster is factory set to level 1.
2) The detected diameter and remaining paper length given in the table are calculated values; there may be discrepancies de-
pending on the rolled state of the paper, the actual mechanism, and the printing pattern.
3) With thick paper (whose thickness is greater than 75 µm) or label paper, the paper roll itself may become loose, causing
errors in detection. So set the adjuster to level 2.
