How to Handle Media
NOTE
Dirty media can affect image quality and reliability of printer output. If you wipe the media with a
tack cloth before printing, it will reduce dust and debris buildup on the carriage underside. The
tack cloth removes static and also removes dust and debris that tend to attract stray ink drops.
Tack cloths are used by auto-body shops to clean cars before painting. Océ does not provide
additional tack cloths beyond what is in the Accessory kit. If you did not receive a cloth or if you
wish to purchase additional tack cloths, they are available at local hardware or auto supply
stores.
Carriage Collision Recovery
If 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 may occur. If a collision occurs, the carriage will
stop and display a message on the User Interface panel. After the operator clears the offending
media from the table and before the next print is started, printhead maintenance must be
performed (See Printer Maintenance section).
How to Handle Media with Uncured Ink
If the UV ink is not properly cured, wear nitrile gloves when you handle prints. This will minimize
the risk of skin irritation and sensitization from possible exposure to uncured ink.
Media Adhesion
Some media have better adhesion quality than others. Factors such as the amount of ink used
and the amount of curing energy from the UV lamps can affect adhesion.
For more information on media adhesion, see Application Bulletin 6 on the customer support
web site.
Media-Related Application Bulletins
For additional information on various aspects of handling and managing media refer to the

Thermal Expansion of Media
When imaging on media that will expand when subjected to heat (e.g., styrene or Plexiglas, 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. If you overprint on media that expands when heat is applied, we recommend
that you group the desired image with the preceding image so the media stays at a consistent
temperature.
Thermal Deformation of Media
Some heat-sensitive media may deform when subjected to high heat. If this occurs you can
reduce the lamp power from the default setting of 7. You can also try to print uni-directional
using only the trailing lamp (to do this set the power of the leading lamp to 0).
