How to Handle Media
Introduction
Océ Display Graphics Systems has conducted extensive testing of many media. Since the Arizona T220UV printer is capable
of imaging on a wide range of material, ODGS encourages you to explore various media so that you can establish your own
criteria for achieving high quality images in your work environment. Please consult the ODGS web site at:

Definition
The term media covers a wide range of possible materials for the Arizona T220UV printer. Essentially, any material that is
less than two inches (5 cm) thick, more than the minimum size of 6” wide x 6” long (15cm x 15cm) and less than the
maximum size of 62” wide x 120” long (158cm x 305cm), can be considered viable media. Some materials will hold the ink
better than others, so we encourage you to experiment with media to determine what works best for your purpose.
Attention:
Do not print on mirrors or any other highly reflective media as UV light is reflected off such media. This results
in curing the ink in the heads and thus damaging them.
Recommendations
■
Store media in the same environmental conditions as it will be used, avoid extremes in humidity and temperature. Store
media flat to reduce tendency to bow.
■
Handle media with lint-free gloves. Oil deposits from fingers will degrade print quality.
■
Ensure the media is free of any debris before you print. If necessary, use the recommended clean-room cloth wipe
(0505-0283 Cloth Poly-Wipe).
Carriage Collision Recovery
If the rotary media touch sensor on the front side of the carriage detects that something on the table is higher than the media
(or if the media is thicker than what is actually set in the print job settings), a carriage collision is about to occur. If a collision
occurs, the carriage will finish its active swath and then pause and flash the message “Pausing Print Please Wait”, followed
by “Media Collision Detected, press ACCEPT to continue”. While this message displays a 15 minute countdown is shown
in the top left corner. This indicates the amount of time the UV lamps will stay on, allowing you to resolve the problem
without shutting the lamps shutting down.
If you press ACCEPT the display shows “Gantry Move: ‘+’ -->Home. ACCEPT: continue CANCEL: cancel print”. If
CANCEL is pressed, the print job is aborted. Press the + key to move the gantry toward the Home position. This allows the
operator to clear whatever caused the collision. Press ACCEPT and you will see the message “Print is Waiting press
ACCEPT to continue”. Press ACCEPT again to allow the carriage to continue to print.
Thermal Expansion of Media
When imaging on media that will expand when subjected to heat (e.g., styrene or plexiglass, etc.), don’t wedge the media
by butting other material against it as this may cause the media to buckle. Also if multiple pieces of the media are used, allow
enough space between the pieces to allow for thermal expansion. Placing tape on the table prior to laying down the media
will prevent ink from being imaged onto the table. Finally, if using overprinting on media that will expand when heat is
applied, we recommend that you group the desired image with a preceding image so the printer is a consistent temperature
when starting to print the desired image.
Note:
Thermal expansion may cause color-to-color alignment problems.
