Paper Sensor Commands
Function Select Paper Sensor(s) to Stop Printing
ASCII [ESC] c 4 <n>
Hexadecimal 1BH 63H 34H <n>
Decimal <27> <99> <52> <n>
Range 0 ≤ n ≤ 255
Description ESC c 4 n selects whether to stop printing or not when the paper low is detected.
There are three sensors in the TM-88 or TM-90 that are simulated in the iTherm
®
280: the paper roll low, paper roll end sensor, and validation sensor. The paper
roll low sensor is enabled when either bit 0 or bit 1 is on. The paper roll end
sensor is enabled when either bit 2 or bit 3 is on. The validation sensor is
enabled when either bit 6 or bit 7 is on. When a paper low or a paper out is
detected, printing stops after printing the current line. The printer goes off line
after printing stops. Installing a new roll starts printing again. The default setting
is n=12. If the paper roll low sensor or paper roll end sensor is disabled and a
paper out is detected, printing does not stop. The printer does not go off line, and
the Paper Out LED comes on. When the validation sensor is enabled and a
paper-end is detected, the printer ejects the paper after printing as much as
possible and enters the paper waiting state. When the validation sensor is
disabled and a paper-end is detected, the printer does not stop printing and eject
the paper. It is possible to select multiple sensors to stop printing. Then when
any sensor detects a paper-end, printing stops. When a paper sensor is enabled
with this command, printing stops only when the corresponding paper is selected
for printing. Print sheet can be selected by using ESC c 0.
Note: The iTherm
®
280 does not allow the paper out sensor to be
disabled.
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 low sensor disabled.
On 01 1 Paper roll low sensor enabled.
1 Off 00 0 Paper roll low sensor disabled.
On 02 2 Paper roll low sensor enabled.
2- 3 — — — Paper roll end sensor enabled (always on)
4-5 — — — Undefined.
6 Off 00 0 Validation sensor disabled.
On 40 64 Validation sensor enabled.
7 Off 00 0 Validation sensor disabled.
On 80 128 Validation sensor enabled.
