1.5.5 Output Tests
Using the output tests you can run motors, energize solenoids and clutches, switch on and off
individual outputs from the high voltage power supply (HVPS), and check the Laser (ROS) motor.
To enter the Output Tests menu see Entering Diagnostics (1.5.2) and Navigating Through
Diagnostics (1.5.3).
In all the tests listed below (Table 1), if the component being tested responds as indicated. then the
circuit wiring to and the component itself are usually good. The problem is most likely the controlling
circuit board or the mechanical components being driven by the tested component.
To make the voltage tests listed in Table 1, open the front cover and remove the drum cartridge.
Cheat the front cover interlock. Initiate the desired test and make the voltage reading between the
component and frame ground.
Do not touch the power supply unit while the power is connected. The POWER switch/inlet
section may be charged even if the POWER switch is turned off.
