HP LaserJet Enterprise MFP M634, M635, M636, M637 - Replace the toner cartridge

This printer indicates when the toner cartridge level is low. The actual toner cartridge life remaining can vary. The toner cartridge does not need to be replaced at this time. Consider having a replacement cartridge available to install when print quality is no longer acceptable.

Continue printing with the current cartridge until redistributing the toner no longer yields acceptable print quality. To redistribute the toner, remove the toner cartridge from the printer and gently rock the cartridge back and forth about its horizontal axis. For graphical representation, see cartridge replacement instructions. Reinsert the toner cartridge into the printer and close the cover.

Do not remove the toner cartridge from its package until you are ready to use it.

  caution:

To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes. Cover the green imaging drum if the toner cartridge must be removed from the printer for an extended period of time.

The following illustrations show the toner-cartridge components.

  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.

note:

Information about recycling used toner cartridges is on the toner cartridge box.
