IMPORTANT
Daily maintenance is important even when white ink or varnish are not
being actively used. Failure to perform daily maintenance can result in
nozzle dropouts or even printhead damage. The purpose of maintenance
is to clean the nozzles of the printheads and thus ensure better image
quality and avoid banding and other print quality issues.
More maintenance is required in dusty environments, or when there are
fibres protruding from the media, or when printing on reflective media
such as glass or metal (more reflected UV light hits the printheads). A
dirty or dusty environment is harmful to the printheads because particles
can plug the nozzles and result in poor image quality. Avoid close
proximity to routers and other sources of dust and debris. Also avoid
placing your printer close to solvent pprinters as the fumes can have a
negative effect on the printheads.
Procedure
1. Agitate the white ink bag gently as described on the bag label at least once
a week.
2.
Perform Printhead Maintenance at least one time every workday and more
often, if required. Do this even if the printer is not used that day.
NOTE
Refer to the Printhead Maintenance section of the Maintenance chapter
for an explanation of how to properly perform daily maintenance. Also,
the complete Printhead Maintenance procedure is documented in a video
that illustrates all of the steps involved and also explains why it is
important to perform regular maintenance. The video can be viewed from
the Customer Support page and is also available to download: http://
dgs.oce.com/. Note that the video discusses the Océ Arizona 550, but the
procedure is the same for the Océ Arizona 400 series printers.
