To clear a head clog go into the driver and go to Start DX Printer Maintenance Tool.
Click on Head Maintenance.
Run a Nozzle Check with Print Check Pattern.
See if there are clogged heads.
If so run a Power Forced Cleaning. Do a Nozzle Check with Print Check Pattern after each cleaning.
It may take 3 Power Forced Cleanings to clear the nozzle.
