Chapter 2 Operation of Diag.
4. The Kind of Diag. and Contents of a Test
4.1 IOT Diag
4.1.1 Digital Input (DI) Test
This function checks whether the DI components operate normally or not.
The DI test is performed for all the DI components.
Exit operation of the DI test makes the control panel display the Customer diag. function menu.
During the DI test, other Customer diag. functions can not be performed simultaneously.
Therefore, the printer does not accept any operation except operations for the DI compo-
nents and exit operation of the DI test.
At the start of the DI test, number “ 0 ” is displayed on the control panel. This number is counted
up when a DI component is turned on from off, therefore it allows the user to know the component
is active.
When a paper jam is occurred, or an error message or code is displayed, execute this test to locate
the damaged parts.
The test will execute the DI Test codes of the components that are supposed to be faulty from the
error details. (Refer to each FIP on Chapter 1.)
Test result: NG (Go to each FIP or replace the parts.)
OK (Turn off/on the main power.)
