1.6 Sensors
1.6.1 Paper Sensors
1.6.1.1 Receipt section
❏
Paper roll near-end sensor:
• The sensor is located on the roll paper supply device on the receipt section. It detects the
near-end of the paper roll by detecting the paper roll diameter. You can adjust the
sensor. See Chapter 5 for details on adjustment.
• When the printer detects a paper near-end, it either stops or continues printing,
depending on the Paper sensor command setting.
• When the sensor is selected to stop printing and the sensor detects a paper near-end, the
printer automatically goes offline after printing the current line. To restart printing, load
the paper and set the printer back online by closing the printer cover. The printer starts
initializing and continues printing data stored in the print buffer.
❏
Paper roll end sensor:
• The paper roll end sensor is located in the paper path on the receipt section. It detects the
presence of paper in the paper path of the printer mechanism.
• When there is no paper in the paper path, the PAPER OUT LED lights.
• When the sensor detects a paper end, printing stops even if it is in the middle of one
transaction; therefore, it is recommended to use the paper roll near-end sensor and use
the paper end sensor as a supplement.
1.6.1.2 Slip section
❏
TOF (Top of Form) sensor: The slip TOF sensor is located in the slip paper path and detects
the presence of slip paper in the paper path. The SLIP LED lights accordingly.
❏
BOF (Bottom of Form) sensor:
• The sensor is located in the slip entrance and detects whether the paper is inserted
correctly and whether it is removed or not. The printer does not proceed to the next
operation until the paper has been inserted correctly or removed. (The SLIP LED
continues blinking.)
• When the printer detects a paper end, it either stops or continues printing depending on
the Paper sensor command setting.
• When the sensor is selected to stop printing, the sensor detects a paper-end and the
printer prints data up to the end of the printable area, ejects the slip when all the next
print data is transmitted, and then waits for the slip to be removed. After the slip is
removed, the printer enters the paper insertion waiting state.
