Paper roll Status commands DLE EOT
Ver. 10.01 p. 308
TM-J2000/J2100
BUSY condition for a parallel interface is selected by memory switch 1-3.
Use this command according to the following rule; otherwise, the status might not be
transmitted.
The next data is not transmitted until status is received when the command of the DLE EOT is
transmitted.
Only when it is necessary to acquire plural, real-time status items continuously, up to 6 DLE EOT
commands can be transmitted continuously. However, the next data is not transmitted until all
status is received in this case.
■ Roll paper sensor status (
n
= 4)
When the roll paper cover is open, paper detection (detected by the roll paper end sensor) may be
incorrect.
■ Ink status A / B (
n
= 7)
When an ink near-end is detected, the INK OUT light blinks. It is possible to print approximately
20,000 characters using Font B with print control mode = economy printing specified from the
time an ink near-end is detected until an ink end is detected. However, the value is only a
reference value, it depends on environmental factors such as printing data, and the timing of
head cleaning. Therefore, replace an old ink cartridge with a new one when a ink near-end is
detected.
TM-J2000 (single-color) does not support ink status B (
n
= 7, a = 2).
Two ink cartridges combined are installed in the TM-J2100 (two-color), and the presence of the
cartridge is detected with one detector. Therefore, both of the following status items are the
same.
Bit 5 of Ink Status A
Bit 5 of Ink Status B
