• Anti-missing Color Mode Does not perform missing dots check after printing each page, but checks missing dots while not printing. Prevents missing colors due to missing dots on the condition with adjoining 2 dots in above and below or 3 dots in all nozzles. Does not perform head cleaning to missing dots with less than 2 dots that are not adjoining.  These functions do not guarantee a 100 percent prevention of dot missing.  Small amount of ink is used for detecting nozzle clogging.  The auto head cleaning is performed automatically after nozzle clogging is detected. Ink is expended during the head cleaning.  Nozzle clogging detect function cannot be disabled.  When you want to select [High Reliability Mode (Reprint)] or [Economy Mode for Low Print Volume (Reprint)], do not uncheck [Use EPSON Status Monitor 3] of [Driver Preferences] in [Driver Utilities] tab. In the High Reliability Mode or Economy Mode for Low Print Volume, printing takes more time since the missing dots check is performed after printing each page. When an unrecoverable missing dot occurs, the printer operates differently for each mode as shown below.
