Next, check the "High" level (voltage) of the I-mark sensor as follows:
1. Pass the media (attached with liner) below the feed roller and media sensor assembly. Align it so
that the media sensor does not detect the I-mark (black mark).
2. Close the print head and the feed roller and media sensor assembly. To get the correct adjustment
result, adjust after you have closed them.
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)
[I-Mark Slice Level]
Set the I-mark sensor slice level.
The setting procedure is as follows:
1. Use the following formula to calculate the slice level:
(High level - Low level) x 0.7 + Low level = slice level
2. Select the [I-Mark Slice Level] in the [Calibrate] menu and press the
button.
3. Press the
/ buttons to change the [Slice level] value. Set the [Slice level] to the slice
level calculated in step 1.
4. Press the
button to confirm the value.
• If you set the [Slice level] to 0.0 (V), the product sets the slice level automatically.
[Head Check]
Automatically check if there is a broken element of the print head.
The options are as follows:
Off
Disable the Head Check.
All
Check the entire print area.
