PL1200 Thermal Transfer Printer
Introduction
2.8 Sensors
There are five sensor locations in the PL1200 labeling unit. The ‘ribbon tape’ sensor is located
between the ‘print head cover’ and the ‘label tension block’ (see diagram 2.8a). This sensor is
used for detection of the thermal transfer ribbon tape. If a ‘no tape’ condition is detected the
PL1200 unit will not print or present labels.
The second sensor is the ‘label alignment’ sensor. This sensor is located between the ‘label tension
block’ and the ‘transfer roller arm’ (see diagram 2.8b). The ‘label alignment’ sensor detects the
labels to properly align the label for printing and pre
sentation.
