The S500 printer uses a QY6-0034-010 Canon Printhead. Printheads are classified as spare parts and as such do not need to be replaced as often as the ink tanks inside the printer. Over a period of time the resistors in the printhead fail and the image quality deteriotes.
When should you replace the printhead?
The printhead does not need to be replaced each time the ink cartridges are replaced, only when print quality deteriotes and a head cleaning fails to resolves the problem, we suggest checking with Canon if you are unsure.
