Chapter 2 Operation of Diagnostic

4.2.3 Digital Output (DO) Test

This function checks whether the Digital Output (DO) components (Motor, Clutch and Solenoid)
operate.
When the interlock is opened while the Motor Test is performed, each component ends to operate.
In this Test Mode, each DO component can be turned individually. Therefore it allows
the CE to check a component's operation from outside, and judge whether the component
is normal or not.
When all the diag. functions are stopped, all the DO components can be turned off.
DO test can make each of the DO component's operate simultaneously.
When a paper jam or PQ problem is occurred, or an error message or code is displayed, this test
enables to look for the broken or damaged parts.
Test result: NG (Go to each FIP or replace the parts.)
OK (Turn off/on the main power.)
