Caution
Do not switch off the UV lamp power supply
unless the lamps have fully completed their con-
trolled cool-down cycle (with fans and heat extrac-
tion). Removing power from hot lamps can result in
overheating and permanent damage. If sudden
removal of power occurs, contact Océ Display Graph-
ics Systems Technical Services before starting the
printer again.
◆ Lamp replacement — the UV lamps will gradually lose their
intensity and therefore their ability to cure the ink. See
"Replacing UV Lamp Bulbs" on page 5-20 or the instruc-
tions included with replacement parts for details.
◆ Unidirectional printing — when printing for long periods in
one direction (unidirectionally), the curing ability of the
lamps will become unbalanced, which could result in insuffi-
cient curing or printing anomolies. To avoid this, occasion-
ally switch between Unidirectional Left and Unidirectional
Right printing (see "Selecting a Print Mode" on page 3-5).
