3.9.1 Run Automatic Adjustment
This function enables the printer automatically to adjust the sensitivity of the paper sensor
according to the paper used. The paper must be properly installed and the PAPER SENSOR MODE
item (see 3.9.2 below) must be selected depending on whether the gap or the black tick mark are
present. At this point, the printer performs a series of actions, at the end of which, if the calibration
sequence is successful, the display shows the blinking message PAPER SENSOR ADJUSTMENT
DONE, otherwise FAILED.
3.9.2 Paper Sensor Mode
This diagnostic function allows the choice of paper sensor.
Press Enter function key to enter in the PAPER SENSOR MODE sub-menu. Press Scroll function
key to scroll through the various items of this function:
- TRANSMISSIVE*: this item enables the transmission mode and must be used when the labels
are marked off by a gap or a hole or more generally when there is an area with a net difference of
support transparency between one label and the other.
- REFLECTIVE: this item enables the reflection mode and must be used when the support is
completely opaque and there is a black tick mark on the back of the support itself.
3.9.3 Paper Sensor Control
This function enables the printer to calibrate the paper sensor manually. This function is useful in
the case of problematic media (e.g. transparent labels).
Press Enter function key and display shows: “Sens Value: nnnn mV” “Gain: nnn Off: nnn”.
Press Scroll function key to change value of “n”.
Press Enter function key to change position of “n”.
Press Esc function key and display shows: “Sens Value: nnnn mV” “Threshold: nnn”.
Press Scroll function key to change value of “n”.
Press Enter function key to change position of “n”.
Press Esc function key to exit.
The value detected by the paper sensor is shown on the first line of the display. To determine the
correct adjustment, it is necessary to maximize the difference between the value detected with a gap
under the sensor and the value with a label. The value (transmissive sensor) is approximately 1200
when there is a gap, 3300 when there is a label and 500 when there is a paper out condition. In any
event, the gap value must be far from that of the paper out value (when nothing appears under the
sensor). Example: Gain: 045 -- Off: 059 Sens Value: label = 3300 gap = 1260 paper out =
550.
The trheshold value must be the Sens Value with label minus 500.
Example: Sens Value: 3300mV Threshold: 280.
3.9.4 Run No Paper Calibration
This function enables the printer to calibrate the paper sensor in paper out condition. This function
is necessary to allows a correct automatic sensor adjustment operation.
Press Enter function key to enter in the NO PAPER CALIBRATION function. At the end of
operation the display shows PAPER SENSOR CALIBRATION DONE or FAIL.
