As with any sophisticated office product, errors may occur and consumable items may need to be
replaced. If this happens, your machine identifies the error or required routine maintenance and
shows the appropriate message. The most common error and maintenance messages are shown
in the table.
You can correct most errors and perform routine maintenance by yourself. If you need additional
