access modes in the event that this threshold requires adjustment to correct registration
issues using different types of die-cut or blow-hole media. The values reported by the
"^D900)" Tick-Tick command will increase when sensing the registration mark and decrease
when the sensor is looking at label and backing of the media. The threshold should be set
to a mid-point between these two points.
2.5.31 ^D681)n
The "^D681)" command is used to set the blackline threshold. The printer's default
threshold is set to "128" and typically does not require any adjustment. The command is
provided in all access modes in the event that this threshold requires adjustment to correct
registration issues with media using a blackline registration mark. The values reported by
the "^D900)" Tick -Tick command will decrease when sensing the black registration mark
and increase when the sensor is looking at more reflective portions of the media. The
threshold should be set to a mid-point between the black mark and more reflective portion.
If the media contains preprint, the threshold should be lowered until proper registration
occurs.
2.5.32 ^D682)n
The "^D682)" command is used to set the stock sensor or out of stock detection. The
printer's default threshold is set to "110" and typically does not require any adjustment. The
command is provided in all access modes in the event that this threshold requires
adjustment to correct the proper detection of stock out conditions. The values reported by
the "^D900)" Tick -Tick command will increase when sensing out of stock conditions The
default threshold is set to a point that should detect most stock out conditions. If the media
contains preprint, the threshold should be increased until proper registration occurs.
2.5.33 ^D690)n
The "^D690)" command is used to set the contrast of the printers output and does not
correlate to actual print head temperature. The value for "n" is a range from 1 to 100 with a
setting of 80 being the printers default. The lowest setting that produces the desired result
should be used to extend print head life and performance.

2.6 7xx Series Commands

The 7xx series commands are used to control configurable enablements. These commands
may be issued either outside or inside a script file. Commands will return the current status
and/or setting if the ^Dxx command is entered without an argument. Entering a question
mark ("?") after the ^Dxx command causes the printer to report the commands current
setting as well as the verbose description and help text associated with that particular
command.
2.6.1 ^D720)n
This command allows scripts stored in the printer's flash memory to be processed on power-
up or a reset condition. The printer has a default power-up script, @default, that will be
used if a script has not been selected using the "^D567)" command. Once a script has been
selected, the "^D720)" command processes the script on power-up as if it was normally
received by the printer.
