Arizona Printer Inks
Introduction
Your Océ Arizona printer uses Océ IJC156 ink, which is easy to maintain. It requires daily
maintenance with a vacuum suction device and a weekly physical cleaning (swabbing) of the
printheads. It also requires small jetting actions (“spitting”) between printing times to keep the
printheads in a ready-to-print state. This spitting action amounts to very little ink usage but does
require that the user clean the maintenance tray covers more frequently. Due to the UV curing
technology, the ink dries immediately, but can take up to 24 hours to cure fully. In most cases, the
printed material may be handled or cut directly after printing.
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. The ink is supplied to the
printer in - 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.
Only qualified inks can be used. If a bag of ink with an invalid serial number, expired use-by date,
incorrect color placement in the ink bay, or if an expired tag is connected to the printer, then the
operator is alerted and an error message is displayed.
The ink delivery system provides the printheads with ink at the appropriate temperature and
pressure. Each printhead has a corresponding ink reservoir on the carriage. Pumps supply ink to
the reservoirs on demand. Sensors in the reservoirs control the level of ink and initiate demand
when required. Ink temperature control is achieved by pumping a coolant fluid through the
printheads. An internal thermostat on each printhead provides temperature feedback.
The condition of the printheads is maintained by periodic cleaning at the maintenance station on
the gantry. During this procedure the operator suctions the printhead nozzle plates, removing ink
and possible contaminates in the process (details of this procedure are available in the
Maintenance section).
