This chapter describes the purposes and functions of this unit and the usage precautions.
1.1. Purpose and Function Description
This unit adopts a non-contact, ink-jet printing method.
It can be used to print various types of outer shapes and materials, such as rough surfaces, uneven surfaces, soft
objects, and fragile objects.
You can set the print description, character type, and character size by using the touch screen or communication
function.
For specific details of each feature, read the respective parts of this instruction manual thoroughly for proper
handling.
1.2. Usage Precautions
1.2.1. Ink and Makeup
(1) Ink and makeup replenishment
This unit employs an automatic ink/makeup replenishment system. While the unit is in operation, the ink
reservoir automatically supplies the ink, and the makeup reservoir automatically supplies the makeup to the
ink main tank at regular intervals. If the ink or makeup replenisher level is too low, an alarm is issued. In this
case, replace the cartridge and replenish the ink or makeup immediately. (For the replenishment procedures,
see Chapter 8.)
* Makeup serves as the replenisher that compensates for an element loss due to ink evaporation during ink
ejection.
It is also used as a cleaning solution.
(2) Periodic ink replacement
For the replacement procedures, see "Technical Manual Chapter 5.3 Replacing the ink".
● While the IJ printer ink circulates during operation, it reacts with the atmospheric air elements and
deteriorates over time. Therefore, it needs periodic replacement. The guide for determining the
replacement interval conforms to the handling guidance of each ink.
