[I-Mark Levels]

Manually set the I-mark sensor level.

The setting procedure is as follows:

First, adjust the "Low" level (voltage) of the I-mark sensor.

1.	Pass the media (attached with liner) between the media sensors. Align it so that the media sensor does not detect the I-mark (black mark).

2.	Close the print head. To get the correct adjustment result, adjust after you have closed the print head.

3.	Select the [I-Mark Levels] in the [Calibrate] menu and press the button.

4.	Press the / buttons to change the [Emit] value until the [Sensor] value is below 0.5 (V). Set the [Emit] value as low as possible.

5.	If the [Sensor] value does not decrease below 0.5 after you changed the [Emit] value, press the / buttons to change the [Receive] value.

6.	Take a note of the [Sensor] value from the above procedure. This is the "Low" level value for the I-mark sensor.

Next, check the "High" level (voltage) of the I-mark sensor as follows:

1.	Pass the media between the media sensors so that the media sensor can detect the I-mark (black mark).

2.	Close the print head.

3.	Check the [Sensor] value.

If the value is 1.0 (V) higher than the "Low" level value you have recorded, this is the "High" level value for the I-mark sensor.

If the difference between the "High" and the "Low" levels is less than 1.0, adjust the [Emit] and [Receive] values so that the difference is more than 1.0, or adjust the "Low" level (voltage) of the I-mark sensor again.

4.	If both "High" and "Low" levels comply with the standard value, press the button to confirm the value.

The standard values for the "High" and "Low" levels for the I-mark sensor are as follows:

◦	Low (without I-mark) ≤ 0.5 (V)

◦	High (with I-mark) - Low ≥ 1.0 (V)
