Align the printheads

Precise alignment between printheads is essential for color accuracy, smooth color transitions and sharp edges in graphical elements.

To align the printheads, go to the HP Internal Print Server and select Printer > Printhead alignment. You can select automatic or manual alignment; the HP Internal Print Server will recommend one or the other, but you can always choose.

Printer calibration

●Automatic alignment is a fully automated procedure that ensures optimal print quality in most cases. The printer prints some patterns and scans them with the built-in line sensor. This is the recommended method for any smooth, high-quality substrates (including vinyl, banners or backlit). If the printheads have many defective nozzles, automatic alignment may not give good results.

The procedure takes about 14 minutes and consumes 9 inches of substrate.

●Manual alignment provides reasonable print quality when automatic alignment is not possible, typically because a highly-textured or non-white substrate is loaded (mesh, perforated, some fabrics, transparent, colored). The printer prints 8 series of patterns, and you must choose the best result from each of the series (for example, number 10 in the picture below).

The procedure takes about 15 minutes and consumes 9 inches of substrate.
