So i havent used my printer in some time. Last time i used it it wouldn't print the magenta so I gave up on it, and put it away. It is a $800 printer and I would like to be able to use it. However now when i do a test print it wont print squat. I have seen various ways of unclogging the heads using windex but I am apprehensive about them. I use this printer for gallery prints and clients. Andy pointer would be great.
