Caution • Adhesives and small pieces of media can over time transfer onto the printer
components along the media path including the platen and printhead. This build-up can
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.
