just curious, after having to replace my print head myself, I'm left with a head with only 172000m dots through it - about 1/8th of it's supposed life. the yellow channel seems to not be coming through very well, the pattern is there and perfect, just not as dark as the new one (which fixed my problems). is there a market for this thing? is there a point in trying the windex/alcohol clean and saving it? I now have two print heads with new warranty and am hopeful that any further replacements are a ways off. anyone want it cheap?
