1-16 Features and General Specifications Rev. A
Slip paper insert sensor
This sensor is located in the slip paper loading path to detect the insertion of slip paper.
Sensor type: Photosensor
Voltage: 5 V DC ± 5%
Input current: Approx. 20 mA
Output level: High when slip paper is detected
Slip paper eject sensor
This sensor is located in the slip paper eject path to detect ejection of slip paper. If ejection is not
detected, the printer does not proceed to the next step.
Sensor type: Photosensor
Voltage: 5 V DC ± 5%
Cover open sensor (*)
This sensor detects the condition of the printer cover. If the cover is open, the printer
automatically goes off-line after the current printing operation and the carriage returns to the
home position at slow speed. The printer goes back on-line when the cover is closed.
Sensor type: Photosensor
Voltage: 5 V DC ± 5%
Input current: 10 mA
Output level: High when cover open is detected
(*) If the paper roll sensor detects the “no paper” condition while the cover is open, semi-
automatic loading can be performed by inserting the paper roll into the paper path.
Auto-cutter sensor
Sensor type: Mechanical contact sensor
Voltage: 5 V DC ± 5%
Current rating: 0.1 to 0.5 mA
Home position sensor
This sensor detects the carriage initial position (on the receipt paper side) and the carriage
abnormal operation.
Sensor type: Photosensor
Voltage: 5 V DC ± 5%
Output level: High when the carriage home position is detected
Carriage sensor
This sensor outputs signal synchronized with the carriage operation, and detects whether the
carriage operation is abnormal.
Sensor type: Photosensor
Voltage: 5 V DC ± 5%
Output level: High when sensor plate is detected
