- Sensor Test
This function checks whether the DI components operate normally or not.
The Sensor Test is performed for all the DI components.
Exit operation of the Sensor Test makes the control panel display the CE diag. function menu.
During the Sensor Test, other CE diag. functions can not be performed
simultaneouly. Therefore, the printer does not accept any operation except
operations for the DI components and exit operation of the Sensor Test.
At the start of the Sensor 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 Sensor 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.)
