Blurry documents and images that appear faded are also signs that it`s time to remove the excess ink.

If your printer or plotter head is built into the printer cartridges, you change your printhead every time you change the ink. If the printheads are built into the printer or plotter, they`re likely to require replacement after long-term use.
If you have a commercial printer for your business, cleaning and maintaining the printhead is important—after all, your printer won`t work if the printhead is broken or clogged. Even with proper care and maintenance, printheads will sometimes need to be replaced.
