4 I-Mark Sensor Level CH1B(+8.4V) - CH1A(GND)
5 CH2B - CH1A(GND) VR1 and VR9 (Fine adjustment)
Low level (Set the no eye-mark point
in the sensor’s) = Less than +0.5V
High level (Set the eye-mark in the sensor’s)
= Low level plus more than +0.9V
High level (with eye-mark point) - Low level
(without eye-mark point) = +0.9V
Low level (Set the label backing liner or centre
hole tag in the sensor’s)
= Less than +0.5V
High level (Set the label and tag in the
sensor’s) = Low level plus more than +0.1V
High level (printing point) -
Low level (gap point) = +1.0V
(VR2 is used for adjusting the
light reception flow. If there is
difference between the high and
low level, adjust VR2 to allow
some level difference.)
