Check the EconoMode settings
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 toner cartridge. If print quality begins to degrade and
is no longer acceptable, consider replacing the toner cartridge.
NOTE:
This feature is available with the PCL 6 print driver for Windows. If you are not using that
driver, you can enable the feature by using the HP Embedded Web Server.
