III. Avoid the Contributing Factors to Premature Printhead Failure
There are several factors that can contribute to the premature failure of a printhead. The following information
identifi es these factors and provides possible solutions.
identifi es these factors and provides possible solutions.
ABRASIVE WEAR
Normal abrasive wear of the printhead’s protective coating occurs due to friction, regardless of
the materials used or the maintenance performed. Once the protective coating is worn away, the
printhead elements will be damaged—resulting in printhead failure. For this reason, the printhead
can be considered a consumable item and may require periodic replacement over the life of the
printer. This abrasion may be more aggressive when the following conditions occur.

Contributing Factor
Recommendation
Use of Direct Thermal Media for Non-
Ribbon Applications
Ribbon Applications
Direct Thermal media
requires the paper surface be in direct contact
with the printhead elements. This increases
friction and can cause a reduction in printhead
life when compared to a similar application
using ribbon. The quality of the media and
its compatibility with the thermal printing is
important.

To minimize abrasion, be sure you are using
high-quality Direct Thermal media from a proven
supplier.

Buildup of Paper Dust
Paper dust can collect
on the platen at the outer edges of the media or
ribbon, creating a grinding wheel effect. This can
abrade the printhead glaze, which will result in
printhead failure.

Clean all paper dust buildup on the platen

media path and clean the platen with a lint-free
cloth and isopropyl alcohol around the entire
circumference of the platen.

Printhead Pressure
Excessive pressure
increases friction on the printhead assembly,
resulting in higher abrasion. Printhead pressure
should be evenly balanced across the media.
A balance of darkness and pressure should
be used to generate an acceptable image on
properly matched materials
resulting in higher abrasion. Printhead pressure

Printers with dual-pressure toggles adjust
both evenly over full-width media or reduced
outboard pressure for narrower widths. This
allows the pressure to focus over the narrow
media more effi ciently.
