Fix ink smears on printouts
If a printout shows smears of ink, for subsequent prints, try using the Clean Ink Smear function from
the printer display. This process takes several minutes to complete. Full-size plain paper needs to be
loaded and will be moved back and forth during the cleaning. Mechanical noises are normal at this
time.
1. Load Letter or A4 unused plain white paper into the input tray.
2. From the printer control panel display, touch Setup.
3. Touch Printer Maintenance, select the desired option, and then follow the on-screen instructions.
NOTE: You can also do the same from the HP printer software or embedded web server (EWS). To
access the software or EWS, see
Open the HP printer software (Windows) on page 16 or Open the
embedded Web server on page 90.
