Welcome to HP forums, I See that you are getting print quality issues.
- Did you make a copy and check if the issue persists?
Meanwhile:
Print a cleaning page.
-
From the Home screen on the printer control panel, touch Setup (
).
-
Touch Service, and then touch Cleaning Page.
-
Load plain, white paper when you are prompted.
-
Touch OK to begin the cleaning process.
-
Try to print again to see if the issue is resolved.
Check the EconoMode settings.
-
From the software program, select the Print option.
-
Select the printer, and then click Properties or Preferences.
-
Click the Paper/Quality tab, and then locate the Print Quality area.
-
If the entire page is too dark, use these settings:
-
Select the 600 dpi option.
-
Select the EconoMode check box to enable it.
If the entire page is too light, use these settings:
-
Select the FastRes 1200 option.
-
Clear the EconoMode check box to disable it.
-
-
Click OK, and then click OK to print the job.
