Adjusting The Paper Near-End Sensor - Citizen CT-S4500 User Manual

3.10 Adjusting the Paper Near-end Sensor

Change the settings of the paper near-end sensor to set the position at which the near-
end of the paper is detected.
1. Open the top cover.
2. Adjust the sensor position by moving the paper near end sensor selector lever while
gently pushing it in. The sensor position differs as follows depending on the core outer
diameter of the roll paper to be used.

Notes:
*Sensor position when shipped from the factory. However, factory settings differ depending on the destination market.
CAUTION
 When the media shaft will be used, the roll diameter detection function of the paper near end
sensor will not function properly so disable MSW2-8 (PNE sensor).
 When the memory switch settings are as follows, the paper near-end sensor is disabled.
MSW4-4 (paper selection): Black mark paper/label media
MSW4-5 (paper position detection method): Label gap detection
 When the memory switches are set as follows, the PNE sensor may not function properly due
to factors such as the shape of the shaft center of the roll paper.
If that happens, disable MSW2-8 (PNE sensor).
MSW4-4 (paper selection): Black mark paper / label paper
MSW4-5 (paper position detection method): Black mark detection
 The diameter of the roll of paper that is detected is an estimate. Some variations may occur
depending on the paper.
 When using the supplied sample roll paper, align the sensor position to position 5.
The paper near end may not be able to be detected correctly with the default sensor position.
