6.3. Uni- and Bi-directional printing
- For Bi-directional printing, both UV lamps need to be used.
(curing is done on the fly in both printing directions)
- For Uni-directional printing, only the right UV lamp will be used.
(curing is only done when the shuttle is moving from right to left)
Depending on the heat-resistance/thickness of your media,
you can set the UV lamp power to “Half” or “Full” power.
By default, “Full” power should be used whenever possible.

Note about UV-lamp life time:
The lamp life time is not only depending on the numbers of hours that a lamp generated
light; Especially gas-discharged bulbs, the type that is used in general on all UV-curing
systems, have a life time that is strongly influenced by the number of times that the bulb
is switched ON and OFF. As a general rule, one can state that switching a bulb ON and
OFF counts for about 40 minutes of head life time.
To maximize the useful life time of a bulb, one should not turn the lamps OFF after having
made a print if a next job will be printed in the coming 20 to 30 minutes; For that,
‘continuous ON’ should be checked in the UV options of the setup menu, and a user only
has to switch the lamps off if the machine will not be used for at least an half hour.
Due to the physics of the lamp discharge lamps, a UV-bulb can also not ignite when it is
hot; For that, the UV-bulb is first cooled down for the set period after a user switched it
off, before the bulb will ignite again if the user turns back on the UV-switch.
