My friend has a 7600 with a propensity for head clogs. I am working on getting her to understand that the printer is designed for constant not intermittent use and to print a little something every day to help "keep the pores open" but in the meantime, there is a stubborn clog of the cl and y channels to clear.
What's the best way to approach this? A series of regular cleaning alternating with a test print? How many rounds before trying a power cleaning? If power cleaning doesn't do it, then what? What do you do between power cleaning attempts? From this forum I'm generally familiar with cleaning procedure (e.g. serial power cleanings are a bad thing, the windex under the head trick), but would like to hear from the old hands who have worked out a reliable routine.
(Fortunately, as a 3880 owner, I don't really have to deal with this sort of thing.)
