IJC256 inks require regular spitting in order to keep nozzles clear for jetting
(IJC255 ink only requires spitting with white ink). This spitting occurs in the
maintenance station at set intervals and ejects ink onto an absorbent foam
pad. This foam pad must be changed as it becomes saturated or else the
ink being jetted will not be fully absorbed. The pad will repel the ink that is
not absorbed, especially if the pad is incorrectly placed too close to
required openings. This rebounding ink will be re-deposited into the
surrounding area and cause soiling of printer components as well as a
greater concentration of ink particles in the air.
For more details on the characteristics of the two ink types and
comparisons of their features, see Application Bulletin 28 - "Selecting
Appropriate Océ Ink for Your Applications: Océ IJC255 or Océ IJC256" on
the customer support web site at http://dgs.oce.com/.
These inks have very little odor, but for optimal safety some ventilation is
needed. The printer should operate in an area where a good standard of
general ventilation is available at 5 to 10 air changes per hour. Mechanical
ventilation must be added where the air changes are under 5 per hour.
Refer to the Site Preparation Guide for minimum space/working room
volume for the printer.
NOTE
Read the section on ink safety called "Safety Guidelines for Ink Material"
before you handle the ink.
The printer is optimized for the specific UV-curable ink supplied by Océ
Display Graphics Systems. The ink is supplied to the printer in 2 liter
collapsible bags that are loaded into the printer by means of quick-change
connectors that are bonded into the top corner. To install on the printer,
the bags are inverted and the quick connect couplers are pushed into their
corresponding female coupling. This opens up the flow path for the ink.
The bags contain tags that identifies them to the printer when they are
loaded. This allows the printer to ensure that the correct ink is loaded.
This method of ink delivery has several benefits over bottles or cartridges:
The self-collapsing bags make it easy to see how much ink remains in each
bag.
• Virtually all the ink is successfully extracted from the bag by the printer,
reducing the otherwise costly waste of usable ink.
• Ink changes are performed without mess or spills, keeping the
environment around the printer clean.
• Ink changes can be performed during printing - this prevents wasted
prints and lost time.
