Check the EconoMode setting
This product has an EconoMode option for printing drafts of documents. Using EconoMode can use less toner.
However, using EconoMode can also reduce print quality. To improve print quality, verify that the EconoMode
setting is deactivated.
From the software program, select the Print option.
Select the product, and then click the Properties or Preferences button.
Click the Paper/Quality tab.
Verify that the EconoMode check box is cleared. If there is a checkmark in the check box, click the check
box to clear it.
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.
