If the nozzle check page does not print satisfactorily, there is a problem with the printer. This could be a clogged ink nozzle or a misaligned print head. See Cleaning the Print Head for details on cleaning the print head. For information on aligning the print head, see Aligning the Print Head.
Print the nozzle check pattern to determine whether the ink ejects properly from the print head nozzle. Note. If the remaining ink level is low, the nozzle check pattern will not be printed correctly.
You can clean the printhead either manually or from your printer or computer. Before you start, you`ll want to perform a nozzle check to ensure your printhead needs cleaning, as this will save ink.
Solutions. First, clean the nozzle using a damp cloth or an alcohol wipe while the nozzle is hot. This may cause some steam but will indeed remove any material clinging to the nozzle. If this doesn`t work, you can also use a wire brush, small blade, or needle to remove any remaining debris from the nozzle.
The reason behind this problem is that some of the old material remains in the extruder due to the lower temperature needs of the new material. As a result, the old filament will not melt completely, and the residue left behind may cause the nozzle to clog in the long run.
Nozzle Check

Check the nozzles if you notice print quality has declined and after cleaning to confirm that the print head nozzles have been cleared. If the nozzle check indicates the print head needs cleaning, you can access the Head Cleaning utility directly from the Nozzle Check utility.

The resulting FINE print heads fit approximately 6,000 nozzles on a chip with an area measuring a mere 20 mm x 16 mm, roughly the size of a thumbprint.
Print head cleaning consumes some ink. To avoid wasting ink, clean the print head only if print quality declines; for example, if the printout is blurry or the color is incorrect or missing.
Print head cleaning takes about thirty seconds to complete. Caution: Never turn off the printer while the processing light is flashing. Doing so may damage the printer.
In the Advanced tab, click on “Printing Defaults”. Now select “Maintenance” tab. 4. Click on “Nozzle Check” to check whether the nozzle has been clogged and you cannot print properly.
