Roll Media Theory of Operations
rolls. The media shafts must be inserted in to the supply media roll and take-up media
core before they can be loaded. The media shafts are inserted manually and are automat-
ically locked in place by a spring-loaded media shaft drive couplers. In order to thread
media from the supply roll to the take-up roll the operator uses a foot pedal to control
the take-up media drive. The foot pedals allow the supply media to be driven forward or
reverse in non-initialized control mode. While media is being driven forward the operator
can manually guide the media under the media tension bar then up and over the platen.
The forward and reverse drive directions can be used to help position the media to facilitate
taping to the take-up media core.
Refer to media threading label on the Roll Media Option for details on how to thread
the media when loading. The media roll can be threaded to print either print side out or
print side in.
Note:
For optimum printing results it is recommended the media be aligned such that no more
than a 1mm offset exists between the supply and take-up media rolls.
The Roll Media Option design does not have a media drive pinch. Therefore, all printing
requires the media to be taped to the take-up media core. Once the media has been taped
to the take-up core the operator selects the icon Initialize.
Media Initialization
A media supply roll must be installed, and media threaded and taped to the take-up core
before you can initialize the media. The media initialization process prepares the printer
for printing after the operator selects the Initialize icon in the Roll Manger. When the
initialization is complete, the system will switch to the initialized control mode and is
ready for printing.
Introduction to Media Unloading
Select the Unload Media icon from the printer software to change the control mode from
initialized to non-initialized. . At this point the supply shaft pays out a small amount of
media until the media tension bar is in the zero position (stationary-sitting on the media
ramp). This is required so the media tension bar does not fall down if the media cannot
be held stationary by the vacuum platen during the cutting process. The Unload Media
command changes the functionality of the foot pedal switches to the following:
During this mode the system monitors the position of the media tension bar and the
supply roll. If upward media tension bar motion or forward supply roll motion is detected,
the move is interrupted, motion stopped, and the user is notified to cut the media or
otherwise remedy the situation.
