Be sure to clean up any residual toner on the Toner Cartridge Holder Assembly
with a dedicated toner vacuum cleaner. Do not clean up toner with a general-
purpose vacuum cleaner to avoid the risk of explosion by igniting the fine
powder. As an additional precaution, be sure to attach a ground cable to the toner
vacuum cleaner to discharge static electricity.
Caution
Take care not to allow toner dust to adhere to the photo sensors located on the
