Ink Filters
The UV ink in your printer is protected from contaminants in the ink by means of ink
filters. These are easily accessed and can be replaced by the operator when they become
blocked with debris (see the Maintenance section "How to Change Ink Filters"). The
expected average lifetime for a filter is approximately 12 months or 11 bags of ink (22
liters). However, some filters can last longer and some will require more frequent replace-
ments due to the ink color (pigment) and varying rates of use.
Note:
A loss of pigment when printing a nozzle check indicates that a filter is clogged and must
be replaced.
How to Store and Handle UV Ink
To ensure good quality images and to extend the life of printheads in your printer, it is
important to have good UV ink management procedures. UV inks must be properly
handled and stored correctly.
Inks must be stored within a temperature range of 15º to 40ºC (59º to104ºF). Exposure
to extreme temperatures will reduce the expected life of the ink.
Do not use ink that is past the expiry date displayed in the Ink System Status menu
(click the Ink icon in the Print Job Control module to view the ink menu).
Perform Printhead Maintenance every day before printing.
Swab the printheads with UV Flush at least once a week (and as needed) to dislodge
any potential buildup of particles or ink.
Access to MSDS Ink Information
MSDS (Material Safety Data Sheets) for each color of ink and the UV Flush are available
on the customer web site at: www.dgs.oce.com/. The information on these sheets is more
detailed than the material found in the section titled "Safety Guidelines for Ink Materials"
in this document. Read and periodically review this safety information to ensure optimal
safe handling procedures and proper emergency responses are followed when using UV
inks and flush.
