• 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 con-
tinued. The LCD displays [NOZZLE CLOGGED].
 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.
