HP Color LaserJet Enterprise M552, M553, M554, M555 - Replace the toner-collection unit

Introduction

The following information provides details about the toner-collection unit for the printer, and it includes instructions to replace it.
The printer indicates when the toner-collection unit is nearly full, and when it is completely full. When it is completely full, printing stops until the toner-collection unit is replaced.
To purchase a new toner-collection unit (part number B5L37A), go to the HP Parts Store at www.hp.com/buy/parts.
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.
