1.4 Various Sensors
Gap Sensor
The feed gap sensor detects a label gap to locate the starting print position of the next label.
The sensor is mounted 4 mm off the center line of the main mechanism.
In case of Label
Black Mark Sensor
The black mark sensor locates the position of label by emitting infrared rays onto the black
mark at the back of the ticket. The sensor is mounted 5.75 mm off the center line of the ticket
roll width on the mechanism.

5
In case of Ticket
The default sensor position is (1) as shown on the figure below. To change to the (2) position,
the customer should notify the manufacturer in advance. There can be only one position for
the sensor. Once the sensor position is agreed upon, it can not be changed afterwards.
Ribbon End Sensor
The sensor detects the end portion of the ribbon. The ribbon end must be transparent.
Peel off Sensor
The sensor detects the backing paper of a label. (Not available for TTP-243E Pro and TTP-244
Pro)
