Section 4. Electric Checks and Adjustments

4.3 DC Power Voltage Checks

To check voltage levels, first check the fuses (Section 6.3) and replace if necessary Then remove the LH cover, (Section 4.2) and perform the following steps.

Addtional equipment required: TP Test Module

Digital Multimeter

STEP PROCEDURE

Refer to illustrations on pages 4-3 through 4-5.

1.Attach the connector from the TP Test Module to the test port on the main PCB. Note correct positioning of connector. Nibs on the connector are placed down in the receptacle on the PCB in the forward position.

2.Attach the ground probe of the multimeter to the TP Test Module Gnd pin.

3.Attach the positive probe of the multimeter to the +SIG pin on the TP Test Module terminal.

4.Turn printer on and rotate the dial to a dial POS on the TP Test Module. Record the values from the Multimeter LCD.

5.Confirm voltages are correct. If not, then replace power supply Refer to Section 6.4.
