nozzles can not be recovered in the printer, remove and clean
the jet pack in the jet recovery station. Follow the
instructions provided with the jet recovery station.
When working with the jet packs, keep the following points
in mind:
Cleaning the jet packs
The UV curing system is an "always on" system. As a result,
a small amount of stray UV radiation may escape from the
lamp housings causing ink to cure in or on the jet packs. EFI
has taken steps to minimize the amount of stray UV
radiation reflecting back to the jet packs. However, it may
occasionally be necessary to clean cured ink residue from the
jet packs.

To avoid ink flow blockage, replace the carriage ink filters
semi annually.
Debris and dried ink on the exterior of the jet pack can
cause droplets to scatter or fire in the wrong direction.
Follow the jet pack cleaning instructions to keep the jet
packs clean and free of contaminants.
Keep the jet plate and the surrounding area clean. Dust
and debris can migrate to the jet surface during cleaning.
Any kind of mechanical damage done to the surface of the
jets will cause degraded print quality and lead to
premature jet failure. Use only EFI-approved, clean room
cloths for wiping the surface of the jet packs. You can
purchase these wipes directly from EFI.
An air bubble in a jet pack will cause jets to lose their
prime. If this occurs, purge and wipe the jet pack as
described in the jet pack clearing procedure.
Oils, salts, or acids from the skin can cause damage to the
jet packs. Do not touch the surface of the jet packs with
your bare hands at any time; always wear nitrile gloves
when working around jets and UV-curable inks.
If the printer is going to be idle for an extended period —
such as overnight — perform the sleep or shutdown
procedure (see page Error! Reference source not
found.Error! Bookmark not defined.). These
procedures will help protect the longevity of your printer's
jet packs.
Always store jet packs in their original packaging.
