For optimum performance, clean the printhead regularly. Take care when handling or 
cleaning the printhead by removing any jewelry that may scratch it, and use a 
grounding strap or anti-static mat to discharge static electricity that could damage the 
printhead.

For 200 and 300 dpi printers: Clean after every roll (1500 feet or 450 m) of thermal 
transfer ribbon or after every roll (500 feet or 150 m) of direct thermal labels.

To start, use only the presoaked (isopropyl alcohol) cleaning swabs provided in the 
preventive maintenance kit (Zebra part number 47362). Open the media cover to 
access the printhead, then open the printhead. Lightly blow or brush away any loose 
dust and lint particles within the print mechanism (such as rollers, media or ribbon 
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. Next, press the swab tip against the printhead and swipe the print elements 
from end to end. Finally, turn the platen rollers while wiping them from side to side. 
Repeat this last step until the swab no longer shows dirt.

Abrasion:  Over time, the movement of media and ribbon across the printhead wears 
through the protective ceramic coating, exposing and eventually damaging the print 
elements (dots).

To avoid abrasion:

• Clean your printhead frequently and use well-lubricated thermal transfer ribbons 

with backcoatings optimized to reduce friction.

• Minimize printhead pressure and burn temperature settings by optimizing the 

balance between the two.

• Ensure that the thermal transfer ribbon is as wide as or wider than the label media 

to prevent exposing the elements to the more abrasive label material.
