NOTE: Cleaning all printheads uses more ink than cleaning a single pair.
NOTE: HP recommends that you purge the ink from the printheads before printing a job if the printer has
been turned off for more than six weeks or if you are experiencing inconsistent colors from print to print
after long storage periods. Purging the ink from the printheads helps to ensure maximum color consistency;
it is not a remedy for poor printhead health.
Align the printheads
Precise alignment between printheads is essential for color accuracy, 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.
In the case of a paper jam, if you have used a custom paper, or if you are experiencing problems with color
accuracy; you might need to align the printheads. See
Align the printheads on page 71.
NOTE: If you experience a paper jam, HP recommends that you reinsert the printheads and align the
printheads.
TIP: Use the same paper you intend to print on to align the printheads. Photo paper is recommended for
the best results. Plain; bond; and thin, coated papers are acceptable, but provide marginal results.
WARNING! Colored papers, glossy canvas, and transparent materials such as translucent bond, clear film,
tracing paper, and vellum are not suitable for aligning the printheads. However, if you must perform
printhead alignment with a material that is not supported, make sure you use a material with the same
thickness as the material you are going to use for printing.
Reinsert printheads procedure
1. If the printhead alignment process is running and the wrong paper is loaded, press the Cancel key on the
front panel.
CAUTION: Do not print if the printhead alignment process has been canceled.
2. Load the paper you want to use. Photo paper is recommended for the best results.
WARNING! Colored papers, glossy canvas, and transparent materials such as translucent bond, clear
film, tracing paper, and vellum are not suitable for aligning the printheads. However, if you must
perform printhead alignment with a material that is not supported, make sure you use a material with
the same thickness as the material you are going to use for printing.
