5.1.1 About Print Head
l Overview
• Ink is discharged from the ink chamber by oscillating piezoelectric elements in the heads. This vibration
waveform uses a variable waveform allowing four gradation levels (L, M, S, None).
• The Slider M PCB sends a discharge timing signal to the Head in sync with the Linear encoder scale
interval. (A head supply voltage is generated to transmit nozzle data.)
