1.2.7. Ink Concentration Control
(1) In this unit, the ink is automatically controlled to maintain optimum concentration
for printing.
(2) If an error occurs in the viscometer used to control ink concentration, note the
following.
(a) There are the following three types of viscometer errors:
- [Inside Temperature Sensor Fault]
- [Viscosity Reading Instable]
- [Viscosity Reading Out of Range]
(b) When [Inside Temperature Sensor Fault] occurs, the unit will enter the fault stop state.
You can restart the unit by pressing Close. However, the setting will be changed not to control ink
concentration based on the measurement result using the viscometer thereafter.
Once the setting of automatic concentration control is canceled, the following message will always
appear at power-on. Press Close to cancel the message and contact your nearest local distributor.

(c) When [Viscosity Reading Instable] or [Viscosity Reading Out of Range] occurs, the unit will not
enter the fault stop state. Printing can continue, but contact your nearest local distributor for
inspection.
