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.

<5>SENSOR ADJ. [REFLECT] 4.8V*

[PAUSE]

<5>SENSOR ADJ. [TRANS.] 2.4V

[FEED] and [RESTART]

<5>SENSOR ADJ. [TRANS.] 4.1V*

[PAUSE]

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.

Voltage at a black mark

Midpoint (Threshold voltage)

Voltage at a print area

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.

<5>SENSOR ADJ. [REFLECT] 3.5V

(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.
