11.5 Photocells
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 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 print module recognizes the opaque place as
gap. This photocell type is used frequently when printing foils.
NOTICE!
When using transmission photocells inverse, the print module
must measure a difference of 2.5 V and for reflection photocells
inverse 1 V between translucent and opaque material.
Otherwise the print module does not recognize a difference
between label and gap (bar).
