Head Nozzle Check
This function allows you to check the nozzles by a printed pattern if they discharge ink
normally. Load paper on the printer before executing the check.
If a “Ink Low” or “Ink Out” status is detected, the printer requires to replace the ink
cartridge before printing the pattern.
NOTE: The pattern is printed even if the initial ink charge is not performed yet.
