Is the Nozzle Check Pattern printed properly?
Print the Nozzle Check Pattern to determine whether the ink ejects properly from the print head nozzles.
Refer to When Printing Becomes Faint or Colors Are Incorrect for the Nozzle Check Pattern printing, Print Head
Cleaning, and Print Head Deep Cleaning.
• If the Nozzle Check Pattern is not printed correctly:
After performing the Print Head Cleaning, print the Nozzle Check Pattern and examine the pattern.
• If the problem is not resolved after performing the Print Head Cleaning twice:
Perform the Print Head Deep Cleaning.
If the problem is not resolved after performing the Print Head Deep Cleaning, turn off the machine and
perform another Print Head Deep Cleaning after 24 hours. When you turn the machine off, do not unplug it
from the power supply.
• If the problem is not resolved after performing the Print Head Deep Cleaning twice:
Ink may have run out. Replace the FINE cartridge.
Check2
When a FINE cartridge runs out of ink, replace it with a new one.
Check3
Is the FINE cartridge installed properly?
If the FINE cartridge is not installed securely, ink may not be ejected correctly.
Open the paper output cover, then remove the FINE cartridges.
Then install the FINE cartridges again. Push up the FINE cartridge until it clicks into place.
When the FINE cartridge is installed properly, you hear an electric sound once.
After confirming that the FINE cartridge is installed properly, close the paper output cover.
Note
• Printed colors may not match screen colors due to basic differences in the methods used to produce
colors. Color control settings and environmental differences can also affect how colors appear on the
screen. Therefore, colors of printing results may be different from those on the screen.
