5 Operating status
ON LINE
is the normal function: the green led is on and the printer is ready to receive
data from the serial line.
PRINT
mode is when the printer is printing: the yellow PRINT led is on, data reception is
suspended and the printer only accepts data for the variable fields. Subsequent print com-
mands cannot be received and stored in the buffer unless the printer has been configured
for “double bitmap” in which case it will continue to receive data for the next label whilst
it is still printing the previous label.
OFF LINE
in this mode the led is off as is the PRINT led (it will flash if there is a sus-
pended print session), incoming data will not be processed and will be stored in the recep-
tion buffer.
6 Led indicators
There are three led indicators on the front panel protected by a membrane:
6.1 POWER LED
This indicator is red and shows that the printer is on.
6.2 LINE LED
This indicator is green and gives information on the Command Interpreter.
Continually on
-indicates that the printer is ON-LINE and can process data received.
Flashes irregularly
–while the Command Interpreter is processing the data in the recep-
tion buffer. The flashing speed is linked to the speed of the data processed and may not be
visible in all cases on the ST4xx series.
Flashes at regular intervals
when data is required to complete a command or to fill in a
variable data filed on the next label to be printed.
Continually off
– when the Command interpreter is not processing data received or be-
cause the printer is OFF-LINE.
6.3 PRINT LED
This indicator is yellow and gives information on the current print session.
Continually off
-when it is not printing and there is no suspended session.
Continually on
-when a print session is in progress, even if the printer is not printing be-
cause it is waiting for data to fill in variable fields.
Flashes at regular intervals
–whenever a print session is suspended for any reason (pause
command, printer error, synchronism with external device, etc.)
