Thanks to all ( be sure i have greatly appreciated all inputs
) . I have ran the heads diagnostic utility . It printed a test page with colors . It showed all colors ( black , yellow , purple sometimes perfect sometimes not ) except blue . After 6/7 cleanings ( i assume too much cleanings
) blue and purple were still not perfect and i ran out of black ink ( though before thee utility was showing something like 25/30 per cent black ink ) . I think there was a problem with both heads and cartridges . Now i"ll have to buy black and color cartridges ( today is 8 may , noone/few people works in my country because of the 8 may 1945 armistice so i could not buy it in stores ) .
