BOCA thermal printer not printing clearly? What causes an empty line/lines in the print out?


There can be a number of reasons why these white lines appear along the feed direction. First try to clean the print head following the Cleaning the print head on a Lemur instructions. If the problem persists the print head may need to be replaced. 


Please create a support ticket and attach an image of the current print out for evaluation.


Normally these white lines should only appear after having printed many tickets (hundreds of thousands). If this problem occurs sooner on your printer, please send original ticket stock to us for inspection.
