HEAD TEST
COUNT
Setting the Head Test Count Press the LEFT BLACK OVAL
key to move to the next digit position, press the RIGHT BLACK
OVAL key to change the value of the digit.
Default: 0000 (disables the test)
Range: 0000 to 9999
The printer periodically performs a test of the printhead
functionality, called a “printhead test” or “head test.” This
parameter establishes how many labels are printed between
these internal tests.
HEAD RESISTOR
Setting the Head Resistor Value Press the LEFT BLACK
OVAL key to move to the next digit position, press the RIGHT
BLACK OVAL key to increase the value of the digit.
CAUTION: This parameter should only be changed by qualified
personnel!
Initial Value: Factory-set to match the printhead shipped with
your printer.
Default Value: 0500
Range: 0500 to 1175
This value has been pre-set at the factory to match the resistance
value of the printhead. It will not need to be changed unless the
printhead is replaced.
CAUTION: DO NOT set the value higher than that shown on the
printhead. Setting a higher value may damage the
printhead!
Before replacing a printhead, look on the bottom of the printhead
element for the label that shows the resistance value (ohm value).
VERIFIER PORT
Setting the Verifier Port Press the RIGHT or LEFT BLACK
OVAL key to display other choices.
Default: Off
Selections: Off, 1 VER-RPRNT, 2 VER-THRUPUT
The auxiliary port is used to determine how the printer will react
to the Zebra on-line verifier. There are currently three operating
conditions for this port:
• Off: The verifier port is off.
• 1 VER-RPRNT ERR: Label reprinted if verifier detects an error.
If a bar code is near the upper edge of the label, the label will be
fed out far enough to be verified and then backfed to allow the
next label to be printed and verified.
• 2 VER-THRUPUT: Allows greatest throughput but may not
indicate a verification error immediately upon detection. May
print from one to three labels before an error is recognized and
printing stops.
For more information on the operation of the optional verifier,
refer to the documentation provided with that option.
