12.5 Printer Test
At the Self Test Menu screen, press the 4 key for Printer Test. The scale will then print a TPH test
label. This label has a checker pattern that can help you find problems with the TPH (Thermal Print
Head.) You should clean the TPH before you try this procedure. Follow the maintenance procedure for
cleaning the TPH. The following pages have samples of problems that can occur.
There are several things that this printout can reveal:
1. The rubber roller may be dirty or have something stuck to it. Also, the roller may be perforated.
2. This is a clear indication that the TPH has been damaged or burned out.
If you need to replace the TPH, please contact the CAS (USA) Service Department.
