Where do you live? In the SW clogging at some times of the year are a real problem. I have decided to turn mine off when not in use. Even in sleep mode there is some slight heat generated that contributes to drying out the heads. At least this seems to be true. In addition I put a guitar humidifier next to the head and cover the printer in plastic when humidity drops very low. These a re just tricks I have learned that work for me.
Good advice. I live in Austin so I have plenty of humidity. The clogging really isn't a problem if I use the printer 3 or 4 times a week. If it's longer than that I get clogged heads. The best advice I found was what I mentioned earlier. I never run the automated cleaning cycle and I print something between cycles instead of just piling up cleaning cycles and this works.
Thanks for the information from both of you. I'm looking down the road at canon or hp for my next printer.
