Caution •

accumulate dust and debris. Failure to clean the printhead, media path and platen roller 
could result in inadvertent loss of labels, label jams and possible damage to the printer.

Important • Using too much alcohol can result in contamination of the electronic 
components requiring a much longer drying time before the printer will function properly.
