Chapter 1 Product Overview 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. Economy Mode for Low Print Volume has been added in Ver.WSN00180 or later of the printer firmware. The firmware version can be checked using Self-test Mode. ("Self-test Mode" on page 198) When the printer driver's version is Ver.1.3.0.0 or earlier, the mode cannot be changed to Economy Mode for Low Print Volume, and the mode cannot be changed from Economy Mode for Low Print Volume to another mode. • 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. 1 • 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 Prefer- ences] in [Driver Utilities] tab. When an unrecoverable missing dot occurs, the printer operates differently for each mode as shown below.
