When a print cartridge approaches the end of useful life, you can continue printing with the current cartridge until redistributing the toner no longer yields acceptable print quality.
note:This video shows an HP LaserJet M1212 Multifunction printer, but the steps are the same for your printer.
caution:To prevent damage to the print cartridge, hold the print cartridge at each end. Do not touch the cartridge shutter or the roller surface.
caution:If toner gets on your clothing, wipe it off with a dry cloth and wash the clothing in cold water. Hot water sets toner into the fabric.
