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.
IMPORTANT: Load A4 and letter in portrait. Do not load them in landscape.
1. Load the paper you wish to use, see Paper handling on page 26. 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
aect alignment.
3. From the front panel, tap , then Printer Maintenance►Align the Printhead.
NOTE: Printhead alignment can also be started from the Embedded Web Server (Tools►Utilities►Print
Quality Toolbox►Optimize and Improve►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 ve 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.
