You need to make sure the capping area/wiper is cleaned thoroughly. Make sure your ink is in date. Try performing a small clean and do a nozzle check, if it is no better to perform a power clean and then another nozzle check, if it is still no better we need to soak the print head in cleaning fluid overnight, Perform another nozzle check after 8 hours soaking. If it is still not resolved contact our office to arrange a site visit.
