Toner consumption
EconoMode uses less toner, which might extend the life of the print cartridge. HP does not recommend
the full-time use of EconoMode. If EconoMode is used full-time, the toner supply might outlast the
mechanical parts in the print cartridge. If print quality begins to degrade and is no longer acceptable,
consider replacing the print cartridge.
