3-4 Ink System Overview
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 technical support
before starting the printer again.
• Lamp replacement — the UV lamps will gradually lose their
intensity and therefore their ability to cure the ink. At that
point, you can switch the lamp intensity from Low to High,
but they will eventually have to be replaced. For details, see
step 5 on page 2-5 and “Replacing UV Lamp Bulbs” on page
6-19.
• Unidirectional printing — when printing for long periods in
one direction (unidirectionally), the curing ability of the lamps
will become unbalanced, which could result in insufficient
curing or printing anomolies. To avoid this, occasionally
switch between Unidirectional Left and Unidirectional Right
printing (see “Configure Printing” on page 2-2).
