Ink Is Not Ejected
Check1
Has the ink run out?
Open the top cover, then check the status of ink lamp.
Check2
Is the orange tape or protective film remaining?
Make sure that all of the protective film is peeled off and the Y-shape air hole is exposed, as illustrated in (A).
If the orange tape is left as in (B), pull the orange tape and remove it.
Check3
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:
Check to see if a particular color's ink tank is not empty.
If the Nozzle Check Pattern is not printed correctly though ink is sufficient, perform the Print Head Cleaning
and try printing the Nozzle Check Pattern again.
• 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 printer and
perform another Print Head Deep Cleaning after 24 hours.
• If the problem is not resolved after performing the Print Head Deep Cleaning twice:
If Print Head Deep Cleaning does not resolve the problem, the print head may be damaged. Contact the
service center.
