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 the front cover, left cover, right cover, front UV shield, or rear UV shield (hereinafter collectively referred to as the "covers") is opened during printing, lamp irradiation 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 cover as directed in the instructions shown on the operation panel. 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.
Left cover / Right cover
Open these covers when performing work such as maintenance of the print heads and surrounding parts. If opened while printing is in progress, the UV-LED device will immediately stop irradiating, triggering an emergency stop.
If the left cover and right cover are damaged or deformed, stop using the printer immediately and contact your dealer or service center.
Front UV shield
Remove and attach this cover when necessary, such as when loading the object to be printed on. If opened while printing is in progress, the UV-LED device will immediately stop irradiating, triggering an emergency stop.
If the front UV shield is damaged or deformed, stop using the printer immediately and contact your dealer or service center.
Rear UV shield
Remove and attach this cover during maintenance on the ionizer (an optional part). If opened while printing is in progress, the UV-LED device will immediately stop irradiating, triggering an emergency stop.
If the rear UV shield is damaged or deformed, stop using the printer immediately and contact your dealer or service center.
Emergency stop buttons
These buttons are used to immediately stop the machine's operation in the event of an unintended movement of the machine due to an incorrect operation, etc. As an example, assume that the covers are open so a worker can perform operations on the machine. Pressing one of these buttons 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 on the operation panel, and all operations of the machine are immediately stopped.
