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 con- structed of 3 vertical dots or more in "Anti-missing Dot Mode" or "Anti-missing Read Mode" to pre- vent misreadings due to missing dots or ink drop distortions. • If an unfixable clogged nozzle occurs during auto cleaning after missing dot detection, the follow- ing 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]. ∗ When the number of missing dots exceeds the permitted amount, a printer error occurs and printing is disabled. 1 • 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 clean- ing. • 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
