my printer started acting up, pics were coming out green, and all the cartridges were full. Someone recommended I do a cleaning, did a deep cleaning. Then....when I went to print something, computer said printer not online. Uninstalled and reinstalled it, it worked....but not for long. So...anyone have any input into how I can fix this problem?? I have a Canon i860.... I do buy my cartridges from online company, had no problems till now...thanks
