CAUTION: When the toner-collection unit reaches the end of its life, the printer will stop printing to avoid
damage to internal parts. You must replace the toner-collection unit to continue printing.
NOTE: The toner-collection unit is designed for a single use. Do not attempt to empty the toner-collection unit
and reuse it. Doing so could lead to toner being spilled inside the printer, which could result in reduced print
quality. After use, return the toner-collection unit to HP’s Planet Partners program for recycling.
CAUTION: If toner gets on clothing, wipe it off by using a dry cloth and wash the clothes in cold water. Hot water
sets toner into fabric.
