Thanks to knowledgeable people here I managed to clear a serious clog in the pigment channel of my i860. It was great to have it printing well again. Unfortunately, when I went to do a nozzle check today, I got the 5 flashing orange lights signal. I had printed last week with no problems except the yellow tank was getting low. I replaced it before starting the nozzle check. I tried the advice for re-setting. The printer wouldn't print because I couldn't resolve the error. I have some other poorly working print heads that I used to replace the former one. When I replaced the print head the orange lights went out and the green light is steady. As soon as I installed the original one it turned to the 5 orange flashes. My quandary now is do I buy a new print head - somewhere around $100 - or do I chuck the whole thing and buy a new printer? I really like this printer but I seem to keep spending money on keeping it going. I also hate the idea of having to buy replacement carts all the time. I'm stuck and need some good advice.
