I have a B8550 printer that within a year started printing terrible. I replaced the ink cartridges I've run all sorts of maintenance on it and the prints still look super bad. Someone has told me that I might need to replace the printerhead. I took out my printerhead but could not find any part numbers. Does anyone know a part number for this replacement printhead. The head holds the C, M, Y and 2 black ink cartridges.

Check out the link below. The part no. you need is CN642A, which you can get from the HP Part Store (this is linked at the top of the document below)
Hope this helps
