NOTICE!
When using reflection photocells you should observe that the
label printer cover is closed and in this way other light (e.g.
working lamp) on the photocell is prevented.
For this photocell type the transmitter is at the top res. the receiver at
the bottom, i.e. the infra-red light is sent from the top. In this way the
label detection is also from the top. This photocell type is used for
standard adhesive labels with gap.
For this photocell type the transmitter and receiver are at the bottom,
i.e. the light is reflected by the label and taken over from the receiver.
This photocell type is used for white (light) continuous labels with a
black (dark) bar. The bar is the separator, i.e. it indicates the position
of gap and in this way the label start.
For this photocell type the transmitter is at the top res. the receiver at
the bottom, i.e. the infra-red light is sent from the top. The label
detection is, same as for the
transmission photocell normal
, from
the top. However, it is printed differently as for normal photocells, in
the translucent place; the label printer recognizes the opaque place as
gap. This photocell type is used frequently when printing foils.
For this photocell type the transmitter and receiver are at the bottom,
i.e. the light is reflected by the label and taken over from the receiver.
This photocell type is used for black (dark) continuous labels with a
white (light) bar. This bar is the separator, i.e. it indicates the position
of gap and in this way the start of label.
NOTICE!
When using transmission photocells inverse, the label printer
must measure a difference of 2.5 V and for reflection
photocells inverse 1 V between translucent and opaque
material. Otherwise the label printer does not recognize a
difference between label and gap (bar).
