Linerless Printing
Linerless media loads the same as models with the standard ‘tear-off’’ bezel or the general cutter
factory options. Go to Loading Roll Media on page 158.
Media Reloading - Clean the printhead and inspect the media path and platen roller for build up of
adhesive and debris. Remove particles with the adhesive side of your linerless media. Lightly touch
the media path and platen roller with the label to lift particles off the exposed area of the platen roller
and the media path areas. Go to Linerless Platen (Drive) Roller on page 241 cleaning procedure.
Don’t remove new media from it’s protective wrapping until you are ready to place it in the
printer. Setting the roll on its side will pick up contaminants and may stick to surfaces.
IMPORTANT: The platen roller can accumulate adhesive on the outer edges of the roller. After using
many rolls of media, these ‘rings’ of adhesive can get dislodged when using printer. These particle clumps
can then get transferred to other areas.
Sending Files to the Printer
Graphics, fonts and programming files can be sent to the printer from the Microsoft Windows operating
systems by using the Link-OS Profile Manager, Zebra Setup Utilities (and driver), ZebraNet ™ Bridge or
Zebra® ZDownloader found on the Zebra Web site:
zebra.com/software.
