Routine maintenance
IMPORTANT
• We recommend that you place the drum
unit and/or the toner cartridge on a clean,
flat, level, stable surface with a sheet of
disposable paper or cloth underneath it in
case you accidentally spill or scatter toner.
• Handle the toner cartridge carefully. If
toner scatters on your hands or clothes,
wipe or wash it off with cold water at once.
• To avoid print quality problems, DO NOT
touch the shaded parts shown in the
illustration.
Note
• Be sure to seal up the toner cartridge
tightly in a suitable bag so that toner
powder does not spill out of the cartridge.
• If you choose not to return your used
consumable, please discard the used
consumable according to local
regulations, keeping it separate from
domestic waste. If you have questions,
call your local waste disposal office. (See
EU Directive 2002/96/EC and EN 50419 in
the Safety and Legal Booklet.)
