1. Media
2. Dummy that makes the head gap between the table and the print head 10 mm or less
3. Print head
4. Head gap from media: Keep to 2 mm or less
5. Head gap from dummy: Keep to 10 mm or less
If you do not use a dummy
Always make sure that the head gap between the table and the print head is 10 mm or less. The
head gap is set according to the media thickness, so the head gap becomes too great in areas not
covered by the dummy. This may cause the UV light to reflect onto the print head and may harden
the ink on the head, resulting in a malfunction.
If the gap is too wide, it may cause turbulent airflow, resulting in printing failure.

Notes on printing under the high head gap
The recommended head gap is 1 mm. If you print under a high-head gap, the amount of ink mist will
increase. The ink can adhere to the irradiation surface of the UV lamp. Printing in these conditions can
make the lamp defective.
When printing with a high-head gap, check the irradiation surface of the UV lamp daily for dirt. To clean
the surface, see “Checking the Dirt on the UV Lamp Irradiation Surface”, Requests for Daily Care and
Maintenance.
The glass of the UV lamp irradiation surface is fragile. Applying excessive force to the glass may break
it.
