I have a Canon 1550 printer I bought in 2003. Until a week or so ago, it printed very well. I work at home and rarely print in color. Last week it wouldn't print in color at all. I'm sure this is related to non-use. So, I used the Cleaning program AND the Deep Cleaner with no results. But, today the printer woudln't print at all and there are 7 amber flsahes on the indicator light which, acording to the manual, means to check the print head. I took the head out and cleaned the contact and the residual ink on it. But, still no luck. The BLACK ink was running low so I replaced that cartridge but still NOTHING - the light keeps blinking. I called Canon and they want $10 just to give me advice. I'm hoping someone on here has a solution. Thanks
