Safety Devices

UV-LED devices are very dangerous because the ultraviolet radiation emitted from UV-LED devices can cause eye damage and skin diseases when directly irradiated on the human body. The machine is fitted with a cover to keep external leakage of ultraviolet radiation at low levels.

Therefore, if either the front cover or the maintenance cover (hereinafter collectively referred to as the "covers") is opened during printing, lamp illumination will immediately cease and operation will stop. At this time, a message is displayed on the operation panel prompting the user to close the cover. Close the covers as directed in the instructions shown on the screen. Also, if print data is received while the cover is open, printing will not begin.

When the cover is closed, you will be able to continue the operation. If you cannot continue the operation even after you close the cover, a nonrecoverable error may have occurred.

Front Cover

This cover absorbs ultraviolet radiation from the UV-LED device and reduces it to a non-harmful level.

If the front cover is damaged or cracked, stop using the printer immediately and contact your dealer or service center.

Maintenance Cover

This cover is opened and closed when the print heads and surrounding components are undergoing maintenance, during disposal of discharged fluid, or when cleaning liquid is being replaced. If opened while printing is in progress, the UV-LED device will immediately stop emitting light, triggering an emergency stop.

If the maintenance cover is damaged or deformed, stop using the printer immediately and contact your dealer or service center.

Emergency Stop Button

This button allows you to stop the machine immediately when it acts unexpectedly due to, for example, incorrect operation. As an example, assume that the front cover is open so a worker can perform operations on the machine. Pressing this button in the event of unexpected machine operation eliminates the hazards presented by such a situation.

For emergency stop, push in the button shown in the figure. "Fatal Error" is displayed in the screen, and all operations of the machine are immediately stopped.

If the print heads are stopped in a position where they are disengaged from the print head caps, turn the power back on within 10 minutes to prevent them from drying out.

To cancel the emergency stop, turn the button clockwise until it stops turning, and then release the button. If the button has been pulled out, the emergency stop has been canceled. After canceling the emergency stop, turn on the power.
