Error messages communicate that some action must be performed, such as adding paper or clearing a paper jam.
Some error messages are auto-continuable. If AUTO CONTINUE=ON is set in the menus, the printer will continue normal operation after displaying an auto-continuable error message for 10 seconds.
Any button pressed during the 10-second display of an auto-continuable error message will override the auto-continue feature and the function of the button pressed will take precedence. For example, pressing the Stop button will pause printing and offer the option cancel the print job.
