Preventive Maintenance
For optimum performance, clean the printhead regularly after every roll of direct thermal labels.
To start, only use the cleaning pen or pre-soaked (isopropyl alcohol) cleaning swabs provided.
Lightly blow or brush away any loose dust and lint particles within the print mechanism (i.e. rollers,
media sensors, and printhead). NEVER use any hard, metallic, or abrasive objects—such as a
screwdriver—to remove adhesives or other contaminants that may have built up on the printhead or
platen roller.
Periodically use the Save-a-printhead cleaning film to remove printhead contamination buildup.
(Part No.105950-047) The need to use cleaning film will very with media used, environmental
conditions and printer settings.
Avoid the Contributing Factors to Premature printhead Failure
Print Head Care
The main factors that contribute to reduced head life are:
♦
Touching the printhead! Static electricity can discharge and damage the printhead. The body's
oils and acids also damage the printhead.
♦Cleaning - For optimum performance, clean the printhead regularly after every roll of direct
thermal labels.
♦Abrasion - Over time, the movement of media/ribbon across the printhead will wear through the
protective ceramic coating, exposing and eventually damaging the print elements (dots).
♦Use of proper media - Use only approved Zebra media. Non-approved media may contain
chemicals or pre-printed inks that can destroy or dramatically reduce the printhead's life.
♦Temperature - printhead density (heat) setting. Set the density to the lowest possible setting that
prints a good image.
♦Print Speed - Fast print speeds have higher friction levels on the printhead's surface.
♦
Regular printhead Conditioning - Use our Save-a-printhead cleaning film to remove
printhead contamination buildup quickly and easily. (Part No.105950-047)
Basic Cleaning
The printer’s media path allows for cleaning and clearing of media jams. The user can clean the
printhead, platen roller and areas adjacent to the media path surfaces.
Keep your printer clean by periodically wiping it with a soft, lint free cloth dampened with 95% or
higher isopropyl alcohol. Do not use abrasive cleaners as they will damage the surfaces.
The cleaning pen is for cleaning the printhead only!
Do not use the cleaning pen for general cleaning.
