If black ink is not jetted out normally, cyan ink can be substituted for black ink in printing.
Page 331 • Selector 7: Unidirectional print for higher print quality The machine prints bidirectionally by default. To get higher print quality, set this selector to "1" to switch to the unidirectional print mode in which printing is performed only when the head/carriage unit travels from left to right. Note that the unidirectional print mode sacrifices the print speed.
Page 332 • Selectors 2 and 3: Auto capping start time If data transfer from the PC stops midway through printing for some reason in the PC, the head/carriage unit automatically returns to the home position (head capping position) after the specified auto capping start time (default: 30 seconds) to prevent the head surface from drying up.
