Checking the Print Head Nozzles
If you find that the printout is unexpectedly faint or that dots are missing, you may be able to identify the problem by checking the print head nozzles.
You can check the print head nozzles from your computer using the Nozzle Check utility in the printer driver or from the printer using the control panel buttons.
Note:|
When you print a nozzle check pattern, use paper with a width of 116.8 mm (4.6 inches) or more.
