Extended System-Level Command Functions
(RD) Reflective TOF Delta – This command allows the manual entry for the control of the low-
level voltage difference level to recognize a label "gap" or "mark."
(RE) Ribbon Saver Equipped – This command allows the printer to sense the ribbon saver
option. A or Y - automatically senses device presence; if undetected, no error is generated. E -
enables the device, where its presence must be detected; otherwise, a fault is generated. N or D -
disables device detection. See <STX>R for command details.
(RF) Row Adjust Fine Tune – This command shifts the vertical start of print position in dots (see
Appendix K) upward or downward to fine-tune the Row Offset setting to compensate for slight
mechanical differences sometimes evident if multiple printers share label formats.
(RG) Reflective TOF Gain – This command allows the manual entry for the control of the
voltage to the LED emitter of the Media Sensor.
