How to Change a UV Lamp
Introduction
The Arizona 250 GT uses two UV lamps, one on each side of the carriage, to
instantly cure the ink during printing. These UV lamps have an expected life of 500
hours and must be replaced by the user when they fail or can no longer cure the ink
at maximum available power. It is recommended that these lamps be replaced in
pairs to ensure even curing in both directions. Each lamp is supplied in a cartridge
that is easy to replace.
When to do
The life expectancy of the UV lamp is 500 hours. Océ recommends that both UV
Lamp Cartridges be replaced simultaneously to ensure that the curing effect is
balanced when printing in opposite directions. In the case of a premature failure or
accidental breakage of one lamp, the operator can decide to replace only one lamp
but should confirm image consistency after the replacement.
