UBI EasyCoder 401 Linerless – Technical Manual
LINERLESS DIRECT THERMAL PAPER
The EasyCoder 401 Linerless printer models are intended for
linerless printing only. Normal direct thermal papers may be used,
but have to be tested in your application.
Linerless label web is provided with an adhesive layer at the back
of the web, which is not protected by any liner (backing paper), just
like a roll of self-adhesive tape. The metallic parts of the printer in
contact with the adhesive are treated with a special coating intended
to prevent the paper to stick to the metal, and the pressing roller has
a special surface for the same purpose. The face side of the label web
is provided with a thin silicon coating, that makes it easier to release
the web from the roll, and provides additional protection to the
printout against mechanical abrasion, moisture, chemicals, and
UV-light.
The characteristics of linerless labels make them less suited for the
printing of ladder-style bar codes, i.e. bar codes where the bars run
across the paper web. For best readability (ANSI A, CEN 4), use
picket fence bar codes only, i.e. bar codes with the bars running
along the paper web.
Linerless printing requires regular cleaning to avoid build-up of
adhesive residue in the print mechanism and the paper cutter. The
following cleaning intervals are recommended:
• Clean the printhead before loading each new roll of paper.
• Check all parts exposed to the adhesive after each 3 km of paper
feed (corresponds approximately to 20 full size paper rolls), and
clean if necessary.
• Clean the cutter at an interval of 50,000 cuts.
Follow the cleaning instructions in the User's Manual for best
printout quality and troublefree performance.
Linerless label materials are available in normal and thin calipers
with normal or high sensitivity. Both permanent and removable
adhesives are available.
UBI offer stock label rolls for direct thermal linerless printing
in a variety of widths and qualities.
Special sizes and qualities can be offered on request.
