Paper Sensor Commands
The TM-U375/U375P supports the following commands for controlling the paper sensor(s) that stop
printing and output paper-end signals:
Command Name
ESC c 4 Select paper sensor(s) to stop printing
ESC c 3 Select paper sensor(s) to output paper-end signals
ESC c 4 n
[Name] Select paper sensor(s) to stop printing
[Format] ASCII ESC c 4 n
Hex 1B 63 34 n
Decimal 27 99 52 n
[Range] 0 ≤ n ≤ 255
ESC c 4 n selects the paper sensor that stops printing when the paper runs out. The default setting is
n=0 (all paper sensors disabled).
If either bit 0 or 1 is 1, the paper roll near-end sensor is enabled to stop printing.
When a paper sensor is enabled with this command, printing stops only when the corresponding
paper is selected for printing. It is possible to select multiple sensors to stop printing. Then if any of
the selected sensors detects a paper-end or near-end, printing stops.
When the paper roll near-end sensor detects a near-end, printing stops after printing the current line
and feeding the paper.
When DIP switch 2-3 is off and the paper roll near-end sensor detects a paper near-end, the printer
goes off-line after printing stops.
When the slip or validation ejection sensor detects a paper-end, the printer ejects the paper after
printing and then enters the paper waiting state.
The paper sensor(s) used to stop printing are selected by using n as follows:
Bit Off/On Hex Decimal Function
0
Off 00 0 Paper roll near-end sensor disabled.
On 01 1 Paper roll near-end sensor enabled.
1
Off 00 0 Paper roll near-end sensor disabled.
On 02 2 Paper roll near-end sensor enabled.
2-4 - - - Undefined.
5
Off 00 0 Slip ejection sensor disabled.
On 20 32 Slip ejection sensor enabled.
