Machine Moves But Ink Is Not Ejected
Check 1: 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
Routine Maintenance 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
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:
If Print Head Deep Cleaning does not resolve the problem, the Print Head may be damaged.
Contact the service center.
Check 2: Has the ink run out?
See An Error Message Is Displayed on the LCD to identify the ink error, and then take the
appropriate action depending on the error condition.
Check 3: Is the orange tape or protective film remaining?
Make sure that all of the protective film is peeled off and the L-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.
