Component tests
Use the procedure below to test various product mechanical and electromechanical assemblies.
Component test (special-mode test)
This test activates individual parts independently to isolate problems.
Each component test can be performed once or repeatedly. If the Repeat option is enabled from the drop-
down menu, the test cycles the component on and off. This process continues for two minutes, and then the
test terminates.
NOTE: The front or side door interlocks must be defeated to run the component tests. Some tests might
require that the ITB and toner cartridges be removed. A control-panel display prompt appears indicate
removing some, or all of the cartridges, during certain tests.
1. From the Home screen on the product control panel, scroll to and touch the Administration button.
2. Open the following menus:
●
Troubleshooting
●
Diagnostic Tests
●
Component Test
3. Select the component test options for the test.
