Chapter 2 Operation of Diag.
4.3 Printer Diag.
4.3.1 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 simultaneouly.
Therefore, the printer does not accept any operation except operations for the DI
components 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.
