Tips on how to avoid printhead failure

Here are the 5 factors that most often contribute to premature printhead failure, plus our tips on how to avoid them:

1. Abrasive wear of the printhead occurs due to friction regardless of label materials used or maintenance performed, causing the printhead to fail. However, with proper care you can elongate the process. Below are some ways in which you can avoid abrasion:

Buildup of Paper Dust: Clean all paper dust buildup on the platen and printhead. If you are to brush or wipe the printhead and platen down, be sure to reference the printer user guide to ensure you are using proper materials.

Printhead Pressure: It is necessary to properly adjust toggles to your printer requirements. With proper adjustments of your pressure toggles, you are allowing the pressure to focus over the narrow media more efficiently.

2. Contamination occurs when media contains or is introduced to abrasive substances that pass through the printhead evidently damaging the protective coating. Once the coating is damaged, the printhead fails. There are certain controllable factors to be conscious of to avoid contamination in your printhead:

Contaminated media: It is recommended that you consult with your media supplier and ensure that you have knowledge of the media you are utilizing with your printer.

Environment: Do your best to protect the media you are using from exposure to contaminants. Consider a protective enclosure for your printer if the location seems to be an issue.

3. Residue buildup of ribbon coating or media coatings on the printhead can interfere with head transfer, causing the printhead to overheat and resulting in printhead failure. Residue buildup can be a direct result of the following:

Improper maintenance: We recommend that you pay close attention to the user’s guide instructions on how to clean and maintain your printer. Be sure to only use proper cleaning accessories.

Excessive darkness settings: We recommend that you use a slower speed for your printer. Doing this extends the life of your printhead while providing better quality.

4. Electrostatic discharge is a sudden flow of electricity between two electrically charged objects caused by contact, or an electric short. This is something to be attentive to as it can severely damage the internal electronic circuitry of a printhead. Some factors that could cause this issue are as follows:

Improper handling: Many printer’s user guides will provide proper instructions on how to care for your printer; this includes specifics on how to avoid electrostatic discharge.

Static buildup: It is recommended that you check to ensure that any static brushes (if applicable) and printhead mechanism wiring are properly secured so static buildup does not occur.

5. If the substances in contact with your printhead become corrosive, they can generate caustic agents when heated, causing printhead failure due to damage to the printhead’s protective coating. There are certain factors to avoid in order to prevent corrosion:

Unapproved media: Consult with your media supplier if you suspect this to be your problem. This is often characterized by the flood coat area of the printhead rapidly failing.

Physically touching the printhead element surface: Try to avoid physically touching the printhead. If you feel it is necessary to, be sure to use correct materials to clean any surface afterwards with an approved cleaning solution before operating the printer.

Improper cleaning: Be sure to only use approved cleaning items for printhead cleaning. Printer user guides will supply proper cleaning instructions.

Pre-printed labeling fits laboratories that manage high volumes of consistent samples and require controlled, repeatable identification. This includes clinical labs processing patient samples, diagnostic labs running standardized assays, and research labs preparing large batches of tubes for studies or long-term storage where data does not change.

Print laboratory labels on demand with real-time data.

Print sample labels as needed using live data from laboratory systems. Generate labels during sample collection, aliquoting, or processing, with unique identifiers, timestamps, and variable data applied at the point of use. This approach supports workflows where sample data changes frequently or requires immediate, accurate identification.
