Caution • Adhesives and media material 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

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.
