3.7 SERVICE MODE (Cont'd)
7.
Observe the threshold level displayed on the LCD and the reading should have increased more than 1.2 V
to the last reading.
The voltage ranges measured should be within the following range:
Media only= 0.3 to 0.7 V
I-mark ≥ 1.2 V
+
Calculate the input threshold voltage using the formula.
(High Voltage Level + Low Voltage Level) x 0.5 = INPUT threshold voltage value
If the measured values are outside this range, you may have trouble in finding a value that will work prop-
erly under all conditions. If this is the case, a higher quality label may be needed to get adequate perfor-
mance.
8.
To set the input threshold, press the LINE button repeatedly until the calculated values displayed. The
maximum voltage can be set is 3.3 V.
If a value of 0.0 V is set, the printer will automatically set the level each time the printer is powered on with
labels loaded or the print head is closed.
9.
Once the setting is correct, pressing the FEED button will accept the setting and advance to the AUTO
ONLINE FEED display.
