Electrical Checks and Adjustments
4-1 Overview
This chapter describes how to check CL608/612 voltage levels and adjust threshold
sensor voltages.
The power supply converts 125 VAC into regulated DC voltages. The printer uses:
+5V and +24V. These DC voltages are not adjustable, however you can measure
these DC voltages at test points located on the PCB. If a voltage is out of
specification, the power supply must be replaced. Section 4-3 contains procedures
for measuring DC voltage levels. Power supply removal and replacement procedures
are located in Section 6-5.
You can adjust threshold voltage levels for label sensors. These adjustments are
made to allow for variations in the characteristics of the labels used with the printer.
If you cannot calibrate the label sensor voltage level within the specified voltage
range, you should reposition the label sensor by following the adjustment procedures
included in this section. After completing the label sensor adjustment procedures,
perform the label sensor voltage level adjustment procedure.
You can check or adjust:
• Power Supply
• Label Sensors
• Ribbon Sensor
• Pitch Offset
• Label Positions
