Canon IP3680\nNew printhead, but problem existed with old printhead. \n\nIf you look at the attached image, on the "Q" value there is only one set of lines. The "Q" values from -5 to +5 are all the same. Not sure what the problem is.\n\nPrinter was given to me about 6 months ago. Before it didn't have this problem.\n\nAlso look at "A" "B" and "C". The alignment value is at -5, it used to align at +1 or -1.\n\nIgnore the bad colors on the image, didn't scan to well. Colors are fine on actual printout.\n\nAny ideas on what to fix, replace, or do?\n\nThanks in advance.
