Specifications

The value printed on that label is added to (plus) or subtracted from (minus) the
“Darkness” value specified on the Configuration Label.
The resulting numeric value (0 to 30) is the best darkness value for that specific
media/ribbon combination.
The value selected can be entered while performing a Media Darkness
Adjustment. The PLUS value can be entered by pressing the UP (FEED) Key,
while the MINUS value is entered by pressing the DOWN (CANCEL) Key the
appropriate number of times. Refer to the Calibration processes described in
Getting Ready to Print.
Optionally, the required relative darkness value can be programmed into the
ZPL II label formats sent to the printer.
MODE Key Self Test
This self test places the printer in the Communications Diagnostics Mode.
Press the MODE Key while turning the AC power switch ON, then send a label
format to the printer. In this mode, the printer prints the ASCII characters and
their corresponding hexadecimal values for any data received from the host
computer. See the example in Figure 3.4.
NOTE: Turn the printer’s power OFF to exit this self test.
FEED, PAUSE, and CANCEL Keys
If these three keys are held depressed at the same time and the power is turned
ON, the printer will enter the Media Sensor and Ribbon Sensor Sensitivity
Adjustment Mode. See Corrective Maintenance for these adjustments.
