System-Level Command Functions
Class Series Programmer’s Manual 26
STX r Select Reflective Sensor
This command enables reflective (black mark) sensing for top-of-form detection of rolled butt-cut,
and fan-fold or tag stocks with reflective marks on the underside. This Media Sensor will detect a
minimum mark of 0.1 inches (2.54 mm) between labels (see the Operator’s Manual for media
requirements). The end of the black mark determines the top of form. Use the <STX>O command to
adjust the print position.
Syntax: <STX>r
Default setting: Edge sensing
STX S Set Feed Speed
This command controls the output rate of the media when the FEED Key is pressed.
Syntax: <STX>Sn
Where:
n
- Is a letter value (see Appendix L).
STX s Set Single Buffer Mode
(Non-Display Models only)
This command, available for backward compatibility, instructs the printer to use single buffer
operation. In single buffer mode, the printer will erase and format all fields. This, in turn, decreases
printer throughput when incrementing, decrementing, or replacement fields are used (see Label
Formatting Commands). See <STX>d.
Syntax: <STX>s
