Recommended action

To ensure optimal print quality, HP recommends replacing the toner cartridge at this point. You can continue

printing until you notice a decrease in print quality. Actual cartridge life may vary. Once an HP toner cartridge

has reached very low, HP's Premium Protection Warranty on that toner cartridge has ended. All print defects

or cartridge failures incurred when an HP toner cartridge is used in Continue at Very Low mode will not be

considered to be defects in materials or workmanship in the toner cartridge under the HP Print Cartridge

Warranty Statement.
