HP LaserJet Enterprise MFP M634, M635, M636 - User Guide

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.
