3.1. Start Operation
This section describes how to start the unit.
Required operations are explained in detail, including the procedure for starting the unit.
3.1.1. Procedure for Starting Operation
CAUTION
●Ink and makeup may contain organic solvents.
When handling ink or makeup, wear protective gloves and goggles so that it does not come in
direct contact with your skin
●People with an implantable pacemaker must be at least 22 cm away from the built-in antenna
part on the back of the unit.
●An LCD touch panel is used for the screen.
Do not press the buttons with unreasonable force.
●If the system shuts down, turn off the main power switch. To turn on the power again and reuse
the system, see "Chapter 5. Emergency Procedures".
Loosen the head cover lock screw and remove the print head cover. Then, check whether or not the print
head cover and the area around the nozzle are soiled by ink.
Since this unit prints by ejecting ink against the print material, the outside and inside of the print head
cover are soiled by splashing of the ink from the print material. To prevent printing problems due to
soiling, check the soiling state and clean the unit where necessary.
See "3.3. Print Head Cleaning" for the cleaning method.
