•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 avail-
able 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 contin-
ued. 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.
