Datamax E-Class Mark II Maintenance Manual

Maintenance and Adjustments

2.1.1 Cleaning the Printhead
If print quality declines (symptoms can include non-compliant bar codes, print dropouts, streaks,
etc.), the typical cause is debris buildup on the Printhead. If not removed, this buildup can lead to
element failure, reducing the service life of the Printhead. Depending upon the media, ribbon, and
printing parameters used, different methods and supplies are recommended to clean the Printhead.
CAUTION
NEVER use a sharp object on the Printhead; damage can result.
Faulty Label:
Streaks (e.g., white lines) in the direction of print can indicate a dirty or
faulty Printhead.
2.1.1.1 Cotton Swab Procedure
This procedure is recommended when using direct thermal media, or thermal transfer media with wax
ribbon.
1. Stop printing. Allow the Printhead to cool.
2. Raise the Printhead Assembly then remove media and ribbon from the printer.
3. Turn OFF and unplug the printer. Using a Cotton Swab moistened (not soaked) with isopropyl
alcohol, gently wipe the entire Printhead surface clean, while paying special attention to the Burn
Line to ensure all buildup is removed. Allow the Printhead to dry.
