Printer Restart / Reboot Commands

^A ^D Command
X 32 Restart Printer (Soft Restart): This command restarts the printer's internal
software. The soft restart command is also used to start using certain non-
volatile system parameters (print head parameter and soft switch commands).
1 143 Restart Printer (Soft Restart): This command instructs the printer to save
statistics stored in RAM to non-volatile flash memory and then actually resets
the printer hardware. Issuing this command is the equivalent of turning the
printer OFF and ON. This command may be used to start using certain non-
volatile system parameters (print head parameter and soft switch commands).

Registration Mark Threshold 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.
The threshold value may be obtained by using the Auto-Size Label command (^D39). A
more in-depth explanation of registration mark sensing and adjusting the threshold value is
found in the 324M/424M Service Manual.
^A ^D Command
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 Gap Detection Sensitivity: This non-volatile command is used
to set the Threshold Value (0-255) at which the printer detects gap, blow-hole,
and/or black line registration marks.
XX 124 Stock Out Threshold: This command restarts the printer's internal software.
The soft restart command is also used to start using certain non-volatile
system parameters (print head parameter and soft switch commands).
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.
5.2.8

Auto-Size Command

The Auto-Size command attempts to automatically calculate important format values for the
label header including LSY, GAP, AGD, SPG, the ^D90 value, and the ^D91 value. The
printer feeds a sample of labels through the GAP sensors and takes an average of the
values it receives. The Auto-Size command uses the appropriate sensors to detect the
registration marks set by the ^D47 command. Before issuing the Auto-Size command,
verify that the ^D47 is set to the proper setting for the media being used.
