Chapter 1 Product Overview • No Missing Dot Detection Mode The auto nozzle check and the auto head cleaning are not performed.  This "Auto nozzle check" system cannot detect 100% of dot missing cases.  In cases extremely high reliability and safety is required, Epson recommends the use of font constructed of 3 vertical dots or more in "Anti-missing Dot Mode" or "Anti-missing Read Mode" to prevent misreadings due to missing dots or ink drop distortions.  If an unfixable clogged nozzle occurs during auto cleaning after missing dot detection, the following operations will be performed.  If missing dots are not less than the auto cleaning conditions even after auto cleaning is repeated , "Print head nozzle clogged" warning occurs.  Auto cleaning conditions during the "Print head nozzle clogged" warning status are available only when a new missing dot error occurs.  Printer behavior during "Print head nozzle clogged" warning status  When the number of missing dots is within the permitted amount, printing can be continued. The LCD displays [NOZZLE CLOGGED]. 1  When the number of missing dots exceeds the permitted amount, a printer error occurs and printing is disabled.  A very small amount of ink is used in the missing dot detection.  After detecting a missing dot, cleaning is performed automatically and ink is also used in the cleaning.  In [Anti-missing Dot Mode], [Anti-missing Read Mode], and [Anti-missing Color Mode] the auto nozzle check is performed at certain intervals, so the auto nozzle check may occur even during printing. 25
