User Manual

Using the System

into the PASSWORD screen, the CHANGE PASSWORD menu would have provided the option of

changing both levels of password:

Change Language

Printing must be stopped to change this option. It allows the user to define which language the

screens and menus are displayed in.

Diagnostic Menu

Allows the user to access certain parameters to confirm correct printer operation.
Entry to the DIAGNOSTICS menu is made by using the up/down arrow keys to locate the Diagnostic

Menu option from the SETUP menu:

Alternatively, a short cut may be used by pressing the [D] key on the keyboard.

The menu option selected will be the one which was selected the last time the DIAGNOSTICS menu

was used.
The options available from the DIAGNOSTICS menu are described in another chapter of this manual

This shows the total time that the printer has added solvent since the printer has been switched on.
