Hi everyone, just joined this website, alot of useful info. Having some issues with my grenadier printer at the moment. Just tried to print black on white vinyl labels and the test is fluffy, also when printing soild colour I will get some banding in differant areas. Heads look ok when a test print, I also have replaced Capping, dampers and pumps, found a small airleak in join at back of machine, Can anyone advise anything else?
