If print quality declines (symptoms include non-compliant bar 
codes, print dropouts, and streaks; see sample label below), the 
typical cause is debris build-up on the printhead. Furthermore, 
when the build-up is not removed it may lead to element failure, 
greatly reducing the service life of the printhead. 
 
A faulty print quality label (shown).  Streaks indicate a dirty or 
faulty printhead. 
 
 
 
 
4.2.1  Cleaning Film Procedure 
 
To clean the printhead: 
 
1.  Turn the Printhead Latch to the unlocked “RELEASE” position. Remove any media installed in the printer. 
 
2.  Load the Cleaning Film in the same manner as the media, (see section 2.3). 
 
3.  Turn the Printhead Latch to locked “PRINT” position. 
 
4.  Press the Control Button several times until the Cleaning Film is fed out of the printer.
