Align the printhead
Precise printhead alignment is essential for accurate colors, smooth color transitions, and sharp edges
in graphical elements. Your printer has an automatic printhead alignment process which runs whenever
a printhead has been accessed or replaced.
You may need to align the printhead after a paper jam or if you are experiencing print-quality
problems.
1.
Load the paper you wish to use, see
. You can use a roll or a cut
sheet; plain white paper is recommended.
CAUTION:
Do not use transparent or semi-transparent paper to align the printhead.
2.
Ensure that the window is closed, as a strong light source near the printer during printhead
realignment can affect alignment.
3.
From the front panel, press , then Image Quality Maintenance > Align printhead.
NOTE:
Printhead alignment can also be started from the Embedded Web Server (Tools > Print
Quality Toolbox > Align Printhead), or from the HP Utility (Windows: Support >
Printhead Alignment; Mac OS X: Information and Print Quality > Align).
4.
If the loaded paper is satisfactory, the printer runs the realignment and prints a realignment
pattern.
5.
The process takes about five minutes. Wait until the front-panel display shows the process
complete before using the printer.
If the printer cannot complete the printhead alignment successfully, you may be asked to clean the
printhead and try again.
