2. CLEANING MODE AND AMOUNT OF INK PURGED
To prevent printing problems due to bubbles, dust, or ink clogging, print head cleaning is performed before the start of printing, except in the following cases:
- Cleaning on arrival: Performed when the access cover is closed.
- Cleaning by dot count: Performed after ejection of paper (or after printing on the back side of paper when auto duplex printing is performed).
<Cleaning mode list>
*1: After the print head moves to the ink tank replacement position at low ink detection,
- when the raw ink amount changes from low to high, the applicable ink tank is considered to have been replaced.
- when the raw ink amount changes from high to low, or the raw ink amount stays unchanged (high or low), it is considered that ink tanks are
not replaced.
