Checking method of UV illumination intensity
4-46
6
Remove the illumination meter bracket from the device.
7
Check the measured value.
• For the reference value of the measurement, see inside of the illumination meter.
Reference value of the measurement
The lamp illumination intensity before shipping and the theoretical value when the cumulative irradiation
time exceeds 500 hours are indicated on the label located inside of the illumination meter.
• When the cumulative irradiation time exceeds 500 hours, the illumination intensity will decrease by
30%.
• After 500 hours have passed, the illumination intensity will not decrease rapidly.
• Even if the cumulative irradiation time does not exceed 500 hours, when the illumination intensity
decreases rapidly, the UV lamp unit may be broken. Contact a nearby sales agency or our business
office.
• You can check the hardening status of the ink by drawing actually on the media. Please refer to
"Checking UV ink curing level" ( P.4-41 ).
• Even if the illumination intensity decreases, it is possible that the ink will harden sufficiently by
changing the setting of the amount of UV light. Please refer to "Adjusting UV light level" ( P.4-42 ).
• The illumination meter bracket is heated by the UV lamp immediately after
checking the illumination intensity and if you touch it, you may suffer burns.
Remove the illumination meter bracket after being cooled fully.
• Do not touch the illumination meter bracket after the illumination intensity
measurement because it is heated by the UV lamp. You may suffer burns.
