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
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.
If the problem is not resolved after performing the Print Head Deep Cleaning twice:
Ink may have run out. Replace the FINE Cartridge.
Check 2: Is the FINE Cartridge installed properly?
If the Ink Cartridge Locking Cover is not closed securely, ink may not be ejected correctly.
Open the Scanning Unit (Cover), open the Ink Cartridge Locking Cover, then close the Ink Cartridge
Locking Cover.
When you close the Ink Cartridge Locking Cover, push the Ink Cartridge Locking Cover until it clicks
into place.

one.
