on the printer control panel
Understand the cartridge-related messages on the control panel and what actions to take.
Cartridge is low: The printer indicates when a toner cartridge level is low. Actual toner cartridge life
remaining may vary. Consider having a replacement available to install when print quality is no longer
acceptable. The toner cartridge does not need to be replaced now.
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 end to end. Reinsert the toner cartridge into the printer and close the cover.
Cartridge is very low: The printer indicates when the toner cartridge level is very low. Actual toner
cartridge life remaining may vary. To extend the life of the toner, gently rock the cartridges back and
forth end to end. Consider having a replacement available to install when print quality is no longer
acceptable. The toner cartridge does not need to be replaced now unless the print quality is no longer
acceptable.
