I don't know about this printer but a lot of printers have a facility for cleaning the print head, it is normally built into the software that came with the printer (not the driver) , on my hewlett Pakard it is in "start/all programs/Hewlett Packard/hp deskjet 930c/toolbox". on selecting this a window appears where you can select the task , either check the ink levels, alter the configuration & Device Services, which is the one containing "clean the print head". obviously you wont have the same headings but maybe something similar. if not try the website and see if you can download the support software.
hope this helps, good luck
