Ink Is Not Ejected - Canon MX390 series Online Manual

Ink Is Not Ejected

• Check 1: When a FINE cartridge runs out of ink, replace it with a new
one.
• Check 2: 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 the head cover opens.
Push up the ink cartridge lock lever to confirm that the FINE cartridge is installed properly.
After confirming that the FINE cartridge is installed properly, close the paper output cover.
If the problem is not resolved, remove the FINE cartridges, then install them again.
Refer to Replacing a FINE Cartridge for how to install the FINE cartridges.
• Check 3: Are the print head nozzles clogged?
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.
