^A ^D COMMAND
2 143 Save Backup 1 and Reboot (Hard Reset): This command operates just like
option 1 above and also saves a second set of configuration parameters into
the first backup position. If the printer powers on and does not detect a
configuration, it will first search the first backup position and restore the
configuration stored in this location. The command may be sent along with the
^A1^D143 command and is typically only sent when the configuration actually
changes.
3 143 Save Backup 2 and Reboot (Hard Reset): This command operates just like
option 1 above and also saves a third set of configuration parameters into
the second backup position. If the printer powers on and does not detect a
configuration, it will first search the first backup position. If it does not find a
configuration in the first backup, it will then search the second backup location
and restore the configuration stored in this location. The command may be
sent along with the ^A1^D143 and ^A2^D143 commands and is typically only
sent when the configuration actually changes.
5.4.6 Registration Commands
While the printer is designed to work with a wide variety of label media, it is sometimes
necessary to adjust the printer’s thresholds in order to obtain proper registration and
operation. The numerical value in which the printer senses a registration mark is referred as
the threshold value.
XX
90 Reflective Detection Threshold: This command is non-volatile and is used
to set the reflective or blackline threshold value (0-255) at which the printer
detects a blackline used for print registration. The default is set to a value of
100 and should work for most media types.
XX 91 Transmissive Detection Sensitivity: This non-volatile command is used to
set the transmissive or GAP threshold value (0-255) at which the printer
detects gap and/or blow-hole registration marks. The default is set to a value
of 30 and should work for most media types.
XX
124 Stock Out Threshold: This command is non-volatile and is used to set the
stock out threshold value (0-255) at which the printer detects an out of stock or
>LOW STOCK< error condition. The threshold is typically set to a value that is
80 percent of the transmissive sensor reading when no media is detected by
the transmissive sensor. This value is calibrated at the factory and should not
require adjustment unless the transmissive sensor has been replaced.
X
129 Auto Set Threshold: This command will cause the printer to scroll 1350 dots,
determine the proper threshold value, and set the nonvolatile threshold for
proper registration. The ^Ax selects either reflective or transmissive detection.
0 Automatically sets the transmissive threshold value.
1 Automatically sets the reflective threshold value.
X
158 Set the Transmissive Dot2Gap Value:
This is the distance of the transmissive sensor, which detects diecut and blow
hole registration marks, to the dot row. This distance is set at the factory and
