Ground must be supplied.
Installed
Printer +5VDC is used (.5 amp maximum)
Drawing more than .5 amps can result in unreliable printer operation.

Slew Label
Media is advanced until the signal goes HIGH and, if not in continuous
mode, the label is positioned at the next available TOF.
5
Toggle /
Pause
The printer pauses when the signal is taken LOW.
6
Reprint
Input
The last label is reprinted exactly, with no increment or time stamp
changes; recommended for use during error conditions. Holding this
signal LOW will result in non-stop printing.

Ribbon Low
Programmable

. Signifies a RIBBON LOW DIAMETER warning
condition.
10
Service
Required
Evoked by occurrences listed under ‘Fault Messages.’
[1]
Active LOW.
11
End Of Print
Programmable
[1]
. Signifies the End of Print (EOP) process.
12
Media Out
Evoked during an Out of Stock condition. Active LOW.
13
Ribbon Out
Evoked during an Out of Ribbon condition. Active LOW.
14
Data Ready
Evoked when a label is waiting to be printed. Then after the printer
receives the SOP signal, printing will begin. For synchronization with the
print cycle, the End Of Print signal indicates the completion of the print
process. Active LOW.
15 Option
Fault
Output
JMP 1
When inactive, outputs will be
pulled up to a voltage determined
by this jumper setting, where:
Pins 1 – 2 = +5VDC;
Pins 2 – 3 = +24VDC; or,
None = A common external
voltage (not to exceed +30VDC)
via external pull-ups (providing a
20K ohm feedback path through
any two outputs).
Evoked during an RFID fault condition. Active LOW.
[1]
Signal directions are given relative to the printer.
[2]
If active with no current print job, “WAITING FOR DATA” will be displayed. Specifying a quantity of 9999 while keeping this signal ON will cause non-stop label
printing, except in single label Imaging Mode, which will cause the printer to stop between labels.
