Printer Commands Chapter 2

2.7 9xx Series Commands
The 9xx series commands are reserved for printer self tests, factory configuration, and
setup commands. Most of the ^D9xx series commands are not available in access modes
lower than SERVICE level. 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.
2.7.1
^D900)d, s (Diagnostic Tic-Tic Mode)
This command is used to enable the tic-tic mode which steps the motor while reporting the
current readings from the registration mark sensors. This command is available in all
access levels. The Tic-Tic mode reports the sensor data based on the current selected
detection method or outside script sensor configuration. The sensor type must be selected
for the desired operation using the “^D636)” command before entering Tic-tic mode.
Pressing the print button cancels this diagnostic mode.

Table 11 ^D900) and ^D902) Parameters
The printer is set up from the factory to sense proper registration with a wide range of
different stocks. However, it may be necessary to adjust the threshold in order to properly
register some media. The ^D680 and ^D681 commands are used to adjust the registration
mark sensor thresholds.
It is highly recommended that the threshold setting only be adjusted as a last resort.
Registration problems may occur with other types of label stock when the threshold setting
has been changed. The ^D900 command is used to determine a threshold value that will
work for a specific media type.
2.7.1.1
Blackline Threshold Calculation Example
Follow the process outlined below for an example to determine the blackline or reflective
sensor threshold calculation. The values reported will vary depending on the different types
of media used.
1. Verify that the sensors are clean and are unobstructed.
2. Load black line media into printer.
3. Establish communication with a terminal emulation program (HyperTerminal, Tera Term
Pro, etc.).
