5. REPLACEMENT AND ADJUSTMENT
5.1 MASTER FEED
5.1.1 THERMAL HEAD VOLTAGE ADJUSTMENT
To maintain the quality of masters and to extend the life of the thermal head.
Adjustment Standard: There are two steps. 1) The output voltage for the thermal head from the power supply unit must be 22.5 volts (r 0.5). 2) The output from the DC/DC converter board is different from one thermal head to another. Refer to the voltage value (X) on the thermal head decal. The output should be between "X-0.1" and "X" volts. NOTE: This adjustment is always required when the thermal head or power supply unit is replaced. 1. Turn off the main switch and remove the paper exit cover plate (4 screws). 2. Disconnect connector CN503 of the power supply unit. 3. Turn on the main switch, and access the SP mode and select output check mode (SP131) No. 41. 4. Press the Print Start key to apply thermal head voltage continuously (60 seconds). 5. Check the voltage between CN503-15 and CN503-12. If the voltage is not 22.5 volts (r 0.5), turn VR1 on the power supply board to adjust the voltage.
