Align the printheads Precise alignment between printheads is essential for color accuracy, smooth color transitions, and sharp edges in graphical elements. Printhead alignment is recommended in these situations: ● After replacing or reseating a printhead. ● When a new substrate is loaded and the printhead-to-paper spacing changes significantly. ● When there are print-quality problems that could be caused by printhead misalignment. To align the printheads, go to the Internal Print Server and click Printer > Printhead alignment. There are two alignment types to choose from, automatic and manual. Printhead alignment can be affected by wrinkles or other substrate deformations in the print zone. Therefore, if the printer has recently been printing, you should wait for some minutes while it cools down. Just in case, the printer advances the substrate before aligning the printheads. Automatic alignment procedure Automatic alignment is a fully automated procedure that ensures optimal print quality in most cases. The printer prints three blocks of patterns and scans them with the built-in line sensor. This method is intended for any smooth, high-quality substrates (including vinyl and banner substrates). Automatic alignment takes about 10 minutes. It is an unattended process, and uses printed substrate with dimensions 33 cm (13 in) wide by 21 cm (8.3 in) high. To launch, go to the Internal Print Server and click Printer > Printhead alignment > Automatic > Align. The picture below shows the scan-axis alignment of each colorant, at a speed of 60 ips.
