Arizona 250 GT Ink
Introduction
The Arizona 250 GT uses UV-curable inks including Cyan, Magenta, Yellow, and
Black. Due to the UV curing technology, the ink dries immediately and the printed
material may be handled or cut directly after printing. The ink part numbers, which
are necessary for ordering more ink, are provided in the table below.
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 per hour are under 5 per hour. The minimum space/working
room volume for the printer is 69 m3 or 2430 cubic feet.
Note: Read the section on ink safety
page 18) before you handle the ink.
The printer is optimized for IJC255 UV-curable ink. 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
without having to reference the user-interface.
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 prevent 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 recorded 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. Float sensors in the
reservoirs control the level of ink and initiate demand when required.
