(Cont.)
The Sensor Adjustment Mode contains sub menus for displaying the
current status of each sensor and for storing “media level” voltage and
“no media level” voltage. Each time the [PAUSE] key is pressed, the
sub menus are displayed sequentially.
Sensor Status Display:
Temperatures being detected by the Print Head Thermistor and the
Ambient Thermistor are displayed.
Black Mark Sensor Status Display:
Voltage being detected by the Black Mark Sensor is displayed.
Black Mark Sensor Adjustment:
Using the media actually used, a “media level” voltage is stored.
Feed Gap Sensor Status Display:
Voltage being detected by the Feed Gap Sensor is displayed.
Feed Gap Sensor Adjustment:
Using the media actually used, a “media level” voltage is stored.
Black Mark Sensor/Feed Gap Sensor Status Display (No media):
“No media level” voltage detected by the Black Mark Sensor/Feed Gap
Sensor is displayed.
Black Mark Sensor/Feed Gap Sensor Adjustment (No media):
“No media level” voltage is stored.
When using the Black Mark Sensor
(1) While “<5>SENSOR ADJ.” is displayed, press the [PAUSE] key
until the message appears.
The displayed value is a real-time voltage being detected by the Black
Mark Sensor.
(2) Measure a voltage at a blank part of media and a black mark,
respectively. At this time, write down the midpoint between both
voltages. (This value is used later for a threshold setting.)
(Example)
Print area = 4.8V, Black mark = 2.4V Midpoint = 3.6V

NOTES:
1. When measuring a voltage of a blank area, be careful not to align a
pre-print with the sensor by mistake.
2. Confirm that there is at least 0.7V difference between the two values.
If the difference in voltage is less than 0.7V, a print start position
cannot be detected. In that case, please consider changing the media
type.
3. Make sure that the Top Cover is closed when measuring the voltages.
