Printhead Alignment (includes PPS Calibration)

The purpose of the Printhead Alignment is to correct the alignment

between the Printheads in order to prevent color misalignment and

print quality defects like banding. Normally the Printhead Alignment

is performed automatically whenever the printheads are replaced.

The Printhead Alignment also contains the Pen to Paper Spacing

(PPS) Calibration which is used to solve Vertical Line Straightness

(VLS) problems. During normal operation, the PPS calibration will

not be performed automatically whenever the Printheads are

replaced, even though the Printhead Alignment will be performed

automatically.

There are two options available when performing the Printhead

Alignment:

 Standard - Use this when only the Printheads need to be aligned.

This Alignment normally takes about 4½ minutes to be

completed and requires media of at least A4/Letter-size (loaded

in landscape).

 Special - Use this when VLS problems have been detected when

printing line drawings on wide media (36" to 42") in Fast Mode.

Using this option the Printer will perform both the regular

Printhead Alignment and the PPS Calibration. This Alignment

normally takes about 11 minutes and requires media of at least

A3/B-size (loaded in landscape).

Perform the Printhead Alignment as follows:

WARNING Make sure you use HP Bright White InkJet Paper (Bond), HP

Coated Paper, HP Heavy Coated Paper, HP High-Gloss Paper,

HP Satin Paper or Plain Paper. If you try to use any other type

of Paper the Printer will not allow you to perform the Alignment.
